# `keyword` — Testing for Python keywords

  Return `True` if s is a Python keyword.

`keyword.``kwlist`

  Return `True` if s is a Python soft keyword.

  New in version 3.9.

`keyword.``softkwlist`

  Sequence containing all the soft keywords defined for the interpreter. If any soft keywords are defined to only be active when particular `__future__` statements are in effect, these will be included as well.
