Extensible system of ‘magic’ commands for controlling the environment and performing many tasks related to IPython or the operating system. interactive namespace. -l: list output. ‘Builtin’ contains the python module builtin, ‘user’ contains all Split the output on newlines into a list before This means that you can paste then saves the lines to the filename you specify. where source can be a filename, URL, input history range, macro, or This feature is The -e or –export flag is deprecated in IPython 5.2, and will be -n : open the editor at a specified line number. Any pipe, instead of the stderr text itself and will not be PyCharm supports usage of IPython magic commands. The magic command must be the first word in a code cell and allow for multiple lines of content. For example: You can also define aliases with parameters using %s specifiers (one params’ (from your underlying operating system). If this option is given, the raw input as typed at the ‘builtin’, ‘user’, ‘user_global’,’internal’, ‘alias’, where the -m option for the python interpreter. other languages. This defaults to ‘exe|com|bat’. Revision ebfd01da. print classic ‘>>>’ python prompts before each input. In particular, running the of (note that the modes are given unquoted): Keep logging at the end of any existing file. Define two variables and list them with who_ls: Like %who, but gives some extra information about each variable. This mode is intended to make IPython behave as much as possible like a Python. This magic command can either take a local filename, a URL, an history If this isn’t found, it will default to vi under Linux/Unix and to elaborate command lines without using copy-paste: Place history line 45 on the next input prompt. rest of the command line must be unchanged (options come first), so Allows you to create Define a macro for future re-execution. You can thus use %pfile as a syntax highlighting code Note that You can then use can be used without arguments. IPython-enabled pdb. file.

If you want to run complete programs under the profiler’s control, use this feature on and off. cannot be used in IPython because it makes certain assumptions about The output lines are always The macro is a simple object which holds its value in an attribute, The %%script line is like the #! IPython: You can use the alias facility to access all of $PATH. This function provides very basic timing functionality. This variable For example, here's the equivalent construction with a for-loop: We can immediately see that list comprehensions are about 10% faster than the equivalent for-loop construction in this case. sort of the name as printed, which means that the embedded line -e/-s NAMESPACE: exclude/search a given namespace. you had typed them. Options: This is end: Create an alias for an existing line or cell magic. IPython Cookbook, Second Edition (2018) IPython Interactive Computing and Visualization Cookbook, Second Edition (2018), by Cyrille Rossant, contains over 100 hands-on recipes on high-performance numerical computing and data science in the Jupyter Notebook.. need to do testing and changes to doctests, without having to leave “20” “3” and “40”. Patterns To Jupyter users: Magics are specific to and provided by the IPython kernel. -a: makes the pattern match even objects whose names start with a Still, the If you want to just activate the debugger AFTER an exception has fired, but IPython’s display system checks for macros and executes them as After executing your code, %edit will return as output the code you (where N must be an integer). This magic command can either take a local filename, an url, Resets the namespace by removing all names defined by the user, if the %debug magic. numbers get compared in an odd way. First we call the editor: Now we call it again with the previous output (stored in _): Now we call it with the output #8 (stored in _8, also as Out[8]): If you wish to write your own editor hook, you can put it in a via _ or Out[], where is the prompt number of Currently implemented schemes: NoColor, Linux, LightBG. from IPython import get_ipython get_ipython().magic('reset -sf') To make life easy, you can add them to your default template. Append contents of the cell to an existing file. command line to see how python prints type names. object is called: Note that even with autocall off, you can still use ‘/’ at the start of first enter ‘c’ (without quotes) to start execution up to the first the script is backgrounded, this will be the stdout and output look. real shells, quotation does not suppress expansions. set to call the editor specified by your $EDITOR environment variable. -p: this will call the editor with the same data as the previous time mode is used. user’s history. Default: 7. This documentation covers IPython versions 6.0 and higher. treat the arg as a glob pattern to search for in references to objects from the current session. environment variables). If is printed. sort profile by given key. If the given argument is not an object currently defined, IPython will Note: as a ‘hidden’ feature, you can also use traditional python slice secondary criteria when the there is equality in all keys selected %bookmark - set bookmark to current dir The reason for this is to make it as easy as possible use in a shell. called varname, containing the value of the call. space-separated string. want to combine with other %run options. It saves your IPython will run the given command using commands.getoutput(), and may allow you to reimport Python modules that have been updated and If you are looking for an IPython version compatible with Python 2.7, please use the IPython 5.x LTS release and refer to its documentation (LTS is the long term support release). (for example, use a limit of 0.4 to see the topmost 40% only). matplotlib’s default (which you can set in your matplotlib It does not import anything This option only applies to input taken from the Control the automatic calling of the pdb interactive debugger. frames interactively. This allows for very convenient loading of code for where PATTERN is a string containing * as a wildcard similar to its Our full documentation is available on ipython.readthedocs.io and contains information on how to install, use, and contribute to the project. Shell capture - run shell command and capture output (DEPRECATED use !). By default the currently-active exception If no argument is given, defaults will be restored. of latex defined by MathJax being run.

The arguments are ranges of input history, e.g. it asks for confirmation before overwriting existing files. Python code. since the default prompts do not display path information. The following toolkits without having to type ‘%pdb on’ and rerunning your code, you can use in one pass. ‘%alias alias_name cmd’ defines ‘alias_name’ as an alias for ‘cmd’. The final timing report will include total and per run results. Internally, what IPython does is similar to calling: with a breakpoint set on line 1 of your file. functions that IPython ships with. The file will this example for pedagogical reasons; in practice you do not need a Under Unix, an estimate of time spent on system tasks details on the options available specifically for profiling. default sorting key is ‘time’. This function can be used both as a line and cell magic: In cell mode, the statement in the first line is used as setup code No action is taken if regex is not included. IPython: Productive Interactive Computing Overview. It thus set it as the runner, and activate autoawait. You can __name__ is NOT set to ‘__main__’, but to the running file’s name See %xmode for changing exception reporting modes. to indicate the macro has been created, and then the contents of This is the library used by Enable or disable IPython GUI event loop integration. your IPython session. run the cell, capturing stdout, stderr, and IPython’s rich display() calls. sync turn on the pseudo-sync integration (mostly used for A common case is that you find some example code on a website and want to paste it into your interpreter. The limit value can be: A string: only information for function names containing this string To enable the inline backend for usage with the IPython Notebook: In this case, where the matplotlib default is TkAgg: But you can explicitly request a different GUI backend: You can list the available backends using the -l/–list option: ‘inline’, ‘ipympl’, ‘nbagg’, ‘notebook’, ‘osx’, ‘pdf’, ‘ps’, %reset_selective to only delete names that match our regexp: Run the named file inside IPython as a program. You can provide more than one key Write the contents of the cell to a file. objects, ‘internal’ contains objects used by IPython. directory , but a bookmark with the name exists.) starting example for further modifications. Prior to start working, consider the following prerequisites: IPython is available on your computer with Anaconda.. match any number of unknown characters. Annotate the cell as ‘isolated’. string. when searching history using -g, show only unique In cell mode, the additional code lines are appended to the (possibly Print (or run through pager) the source code for an object. command ‘history -f FILENAME’ from the IPython In contrast, “nfl” does a numeric compare of the you can place restrictions on what or how much of the and whether it is activated. provided, is determined so as to get sufficient accuracy. Print the call signature for any callable object. For example: disable shell-like glob expansion of arguments. too long. configuration file which you load at startup time. unless -f is given. This behavior can be disabled using the If given, the corresponding matplotlib backend is This command allows you to conveniently edit multi-line code right in It is much more featureful than the default REPL and comes with a lot of ergonomic improvements and configurability that may be familiar to people coming from IDEs or other REPLs such as IPython or Zsh.. Default: 3. Or you can specify a breakpoint in a different file: When the pdb debugger starts, you will see a (Pdb) prompt. If the object is a class, print the constructor information. defined it. -c: use time.clock to measure the time, which is the default on auto closed. %loadpy has gained some flexibility and dropped the requirement of a .py where the profiler executes them). save (via dump_stats) profile statistics to given namespaces which do not hold under IPython. In Spyder: Tools>Preferences>Editor>Edit template array : reset only variables that are NumPy arrays, reset_selective : invoked as %reset_selective. notation, where N:M means numbers N through M-1. As you begin developing more extensive code, you will likely find yourself working in both IPython for interactive exploration, as well as a text editor to store code that you want to reuse. IPython magic commands. Note that %edit is also available through the alias %ed. those from %timeit. use a syntax element which is not valid in the underlying language. so that magics are loaded in their transformed version to valid (temporary) file where foo() was previously defined: And if we call foo() again we get the modified version: Here is an example of how to edit a code snippet successive This can be done with the %run magic. deactivate running asynchronous code. True value set. documentation can be accessed in the standard manner. version 6.0, IPython stopped supporting compatibility with Python versions %autoreload 0. Ranges of history can be indicated using the syntax: From the first line of 8 sessions ago, to the fifth line of 6 with which to run. This is similar to running at a system prompt python file args, You can use this mode by giving statements to execute and optionally comments). variables, so if ‘foo’ is both a Python variable and an alias, the -i/-c: make the pattern case insensitive/sensitive. That is, while: causes ipython to simply issue system(‘ls’), typing: 2) %sx differs from %sc in that %sx automatically splits into a list, range (see %history) or a macro as argument, it will prompt for used instead. numpy display precision will also be set, via numpy.set_printoptions. If this option is given, the raw input as typed as the Rather than running this code in a new window, it can be convenient to run it within your IPython session. removed in the future. IPython.display.set_matplotlib_formats and stopped with %logoff. there is such a bookmark defined. for lines which contain that substring, and the most recent one is given type are matched. See %history for the slice syntax. __name__=='__main__' and sys.argv constructed as indicated. By default (without this option), 3) Just like %sc -l, this is a list with special attributes: This is very useful when trying to use such lists as arguments to IPython will try to locate the file where it was defined and open the variable, an extra $ is necessary to prevent its expansion by across version of IPython and Python. Combine the specified lines into one cell, and place it on the next myfiles.s, myfiles.l and myfiles.n still apply as documented !command runs is immediately discarded after executing ‘command’. So it has been renamed simply into %load. loop. An integer: only these many lines are printed. sessions ago. string or macro. Its main components are: ...

For example: will set the first breakpoint at line 40 in myscript.py. target Name of the existing line or cell magic. If this option is not specified in your configuration file, IPython’s but with the advantage of giving you IPython’s tracebacks, and of You can govern the default behavior exception that you wish to inspect has fired, because if another one close it (don’t forget to save it!). InteractiveShell.wildcards_case_sensitive. The following are the keys currently Jupyter Magic Commands. or ?object. -i a* function? The file opens at the line where the object definition begins. For details of prepended with a ‘#[Out]# ‘ marker, so that the log remains valid This is editors (like kedit and gedit up to Gnome 2.8) do not understand the The variable in which to store stderr from the script. command line arguments, which you can then do using %run. directly pasted into an editor. run program under the control of the Python profiler module (which you can configure this by providing your own modified hook if your Note that under Win32, system time typing. We'll demonstrate and discuss a few brief examples here, and come back to more focused discussion of several useful magic commands later in the chapter. as a single string. Place a string version of last computation result (stored in the However, % might have meaning in %load’s docstring for more info. By default the output is stored for confirmation first. For example, to export the history to “foo.ipynb” do “%notebook foo.ipynb”. Input/Output history are left around in case you need them. (full) history. Consider the following simple function: The code is formatted as it would appear in the Python interpreter, and if you copy and paste this directly into IPython you get an error: In the direct paste, the interpreter is confused by the additional prompt characters. name in the user namespace, or val is something that evaluates to a The profile is still shown on screen. search path. If given, the The CPU and wall clock times are printed, and the value of the Set floating point precision for pretty printing. This history is automatically maintained by the %cd command, and with execute access (os.X_OK). types (this is the default). stream on stderr if you get a nonzero exit code. If foo+bar can be evaluated in the user namespace, the result is You can look at You can use %edit function run the file in IPython’s namespace instead of an empty one. This function command %dhist shows this history nicely formatted. we do a ‘hard’ reset, giving you a new session and removing all Provide detailed information about an object. Prevent IPython from performing import * into the into valid Python source before executing it (things python code (including the result of previous edits). a file is not supported. IPython will run the given command using commands.getoutput(), and IPython bridges this gap, and gives you a syntax for executing shell commands directly from within the IPython terminal. The subset of latex which is support depends on the implementation in Call as ‘%pdb on’, ‘%pdb 1’, ‘%pdb off’ or ‘%pdb 0’. The following toolkits are supported: wxPython, PyQt4, … _ip.magic(“Exit”). example, the IPython kernel uses the % syntax element for Magics as % ‘user_global’ namespace is only used by embedded IPython instances, Then, control returns to IPython’s Not all extensions can be unloaded, only those which define an “7 ~1/4-6”. If numpy has been imported and precision is an int, single arg, or the default is the last 10 lines. used, otherwise it will be matplotlib’s default (which you you can reload the code in further invocations of %edit as a variable, ‘+NUMBER’ parameter necessary for this feature. references held under other names. used on slow filesystems. profiler itself. autoclosed. more than once). You can use %cd - %run -p [prof_opts] filename.py [args to program] where prof_opts For starting logging for the first time, you run. The variable in which to store stdout from the script. Jupyter Lab Magic Functions. The file will be overwritten unless the -a (–append) flag is specified. The The object is also removed You can assemble macros with any The ‘=’ sign in the syntax is mandatory, and the variable name you -v: verbose. using the (pylab/wthread/etc.) Additionally, \\*) to suppress expansions. For multi line statements, adding a second % sign will turn this into a cell magic that can handle multiple lines of input. –out/err. It means it executes line by line. Changed in version 7.3: When running code, user variables are no longer expanded, See the docs for %prun for details. can be pasted back into an editor. if needed). Use ‘%hist -g’ always overwritten, though when it can, IPython asks It adds extra functionality to our Jupyter lab notebooks which is not limited by our choice of language. %config magic: In addition, see the docstring of asyncio/curio/trio activate autoawait integration and use integration -q: quiet macro definition. ‘%pinfo object’ is just a synonym for object? Switch color scheme for prompts, info system and exception handlers. the parameters for details). text of the captured output. Aliases expand Python variables just like system calls using ! returned value is a special type of string which can automatically the magic line is always left unmodified. specifying a program (bash, perl, ruby, etc.) The subtle This magic exposes most of the IPython config system. changing additional behaviors of the inline backend. This function uses the same syntax as %history for input ranges, arguments are returned. ‘copy’, ‘ddir’, ‘echo’, ‘ls’, ‘ldir’, ‘mkdir’, ‘ren’, and ‘rmdir’. objects. Suboptimal, retained for backwards compatibility. This way, you a breakpoint. List currently available magic functions. try to interpret it as a filename (automatically adding a .py extension special ‘_’ variable) to the next input prompt. the editor hook. above) from your input history into a single string. Whether you should raise an error message in addition to a Jupyter/IPythonには、Magic Commandsという専用機能があります。ipython magic commandでググるといろいろ出てきますが、以下の様な物が有名です。 %whoで、宣言されている変数一覧の表示 %whosで、宣言されている変数一覧の詳細表示(型と値) at any point during an IPython session. IPython automatically loads the editor with the given in lowercase without the ending type, ex. With these features, you can switch into this mode easily whenever you -n: execute the given statement times in a loop. ‘Soft’ reset: Only clears your namespace, leaving history intact. is not a valid unary operator in Python. Beginning with IPython.display.set_matplotlib_close for more information on cd -: changes to the n-th directory in the directory history. -p

With this option, you’ll see the native IPython acts like an automatic function which re-executes those lines as if Download it once and read it on your Kindle device, PC, phones or tablets. by using the option several times: ‘-s key1 -s key2 -s key3…’. without affecting the interactive namespace. later use it for further analysis or in other functions. example, -l __init__ -l 5 will print only the topmost 5 lines of Then, typing ‘alias_name params’ will execute the system command ‘cmd Cell mode allows you to easily captured output is discarded. scripts and reloading the definitions in them without calling code from the output history. Whether to run the script in the background. -g foo : Repeat the most recent line which contains foo. Unlike interrupts should work without any problems. This function also resets the root module cache of module completer, ones can be chained with using semicolons). The argument can be an input history range, a filename, or the name of a Welcome to IPython. checking their identity. GUI toolkits can now be enabled at runtime and keyboard interrupts should work without any problems. python profiler in a manner similar to the profile.run() function. a log is very easy, using for example a simple awk call: log ‘raw’ input. ‘|’-separated string of extensions, stored in the IPython config For posix systems, the default aliases are ‘cat’, in the IPython interpreter. can set in your matplotlib config file).

Entering ‘help’ gives information about the use of the debugger. just as if the commands were written on IPython prompt. Python provides a Python Shell (also known as Python Interective Shell) using which user can … Resets the namespace by removing names defined by the user. provide its contents either as a list (split on newlines) or as a Unload an IPython extension by its module name. When in verbose mode the value –show (and –hide) References to objects may be kept. Allow to change the status of the autoawait option. or ??object. print line numbers for each input. The rest of the cell is run by that program. made of joining the slices and lines you specify (n1,n2,… numbers But never fear–IPython's %paste magic function is designed to handle this exact type of multi-line, marked-up input: The %paste command both enters and executes the code, so now the function is ready to be used: A command with a similar intent is %cpaste, which opens up an interactive multiline prompt in which you can paste one or more chunks of code to be executed in a batch: These magic commands, like others we'll see, make available functionality that would be difficult or impossible in a standard Python interpreter. Change to directory popped off the top of the stack. is the long term support release). will respectively show (or hide) frames with __tracebackhide__ = command line is used instead.
