Warning
This documentation is for an old version of IPython. You can find docs for newer versions here.
Subclass of InteractiveShell for terminal based frontends.
Bases: IPython.core.magic.Magics
Toggle autoindent on/off (if available).
Paste & execute a pre-formatted code block from clipboard.
You must terminate the block with ‘–’ (two minus-signs) or Ctrl-D alone on the line. You can also provide your own sentinel with ‘%paste -s %%’ (‘%%’ is the new sentinel for this operation)
The block is dedented prior to execution to enable execution of method definitions. ‘>’ and ‘+’ characters at the beginning of a line are ignored, to allow pasting directly from e-mails, diff files and doctests (the ‘...’ continuation prompt is also stripped). The executed block is also assigned to variable named ‘pasted_block’ for later editing with ‘%edit pasted_block’.
You can also pass a variable name as an argument, e.g. ‘%cpaste foo’. This assigns the pasted block to variable ‘foo’ as string, without dedenting or executing it (preceding >>> and + is still stripped)
‘%cpaste -r’ re-executes the block previously entered by cpaste.
Do not be alarmed by garbled output on Windows (it’s a readline bug). Just press enter and type – (and press enter again) and the block will be what was just pasted.
IPython statements (magics, shell escapes) are not supported (yet).

Pasting code; enter '--' alone on the line to stop.
:>>> a = ["world!", "Hello"]
:>>> print " ".join(sorted(a))
:--
Hello world!
Paste & execute a pre-formatted code block from clipboard.
The text is pulled directly from the clipboard without user intervention and printed back on the screen before execution (unless the -q flag is given to force quiet mode).

Rerun a previously pasted command.
Execute a block, or store it in a variable, per the user’s request.
Bases: IPython.core.interactiveshell.InteractiveShell
Ask the shell to exit. Can be overiden and used as a callback.
The bottom half of the syntax error handler called in the main loop.
Loop until syntax error is fixed or user cancels.
Switch amongst GUI input hooks by name.
Handle interactive exit.
This method calls the ask_exit callback.
Closely emulate the interactive Python console.
Start the mainloop.
If an optional banner argument is given, it will override the internally created default banner.
Write a prompt and read a line.
The returned line does not include the trailing newline. When the user enters the EOF key sequence, EOFError is raised.
Optional inputs:
- prompt(‘’): a string to be printed to prompt the user.
- continue_prompt(False): whether this line is the first one or a
continuation in a sequence of inputs.
