Warning
This documentation covers a development version of IPython. The development version may differ significantly from the latest stable release.
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).

- class IPython.core.builtin_trap.BuiltinTrap(**kwargs: Any)¶
Bases:
Configurable

- Parameters:
config (Config) – If this is empty, default values are used. If config is a

Notes
Subclasses of Configurable must call the

method ofConfigurable
before doing anything else and usingsuper()
:class MyConfigurable(Configurable): def __init__(self, config=None): super(MyConfigurable, self).__init__(config=config) # Then any other code you need to finish initialization.
This ensures that instances will be configured properly.
