Important

This documentation covers IPython versions 6.0 and higher. Beginning with version 6.0, IPython stopped supporting compatibility with Python versions lower than 3.3 including all versions of Python 2.7.

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).

ZMQInteractiveShell.autoawait¶

Automatically run await statement in the top level repl.

Trait type:: Bool

ZMQInteractiveShell.autocall¶

Make IPython automatically call any callable object even if you didn’t type explicit parentheses. For example, ‘str 43’ becomes ‘str(43)’ automatically. The value can be ‘0’ to disable the feature, ‘1’ for ‘smart’ autocall, where it is not applied if there are no more arguments on the line, and ‘2’ for ‘full’ autocall, where all callable objects are automatically called (even if no arguments are present).

Options:: 0, 1, 2
Default:: 0

ZMQInteractiveShell.cache_size¶

Set the size of the output cache. The default is 1000, you can change it permanently in your config file. Setting it to 0 completely disables the caching system, and the minimum value accepted is 3 (if you provide a value less than 3, it is reset to 0 and a warning is issued). This limit is defined because otherwise you’ll spend more time re-flushing a too small cache than working

Trait type:: Int
Default:: 1000

ZMQInteractiveShell.color_info¶

Use colors for displaying information about objects. Because this information is passed through a pager (like ‘less’), and some pagers get confused with color codes, this capability can be turned off.
