In addition, Python also has 3 soft keywords. Unlike regular hard keywords, soft keywords are reserved words only in the limited contexts where interpreting them as keywords would make syntactic sense. These words can be used as identifiers elsewhere; You can define a function or variable named match or case.[6][7]
_[note 4]
case[note 4]
match[note 4]
Notes
async and await were introduced in Python 3.5.[5]
True and False became keywords in Python 3.0. Previously they were global variables.
nonlocal was introduced in Python 3.0.
match, case and _ were introduced as keywords in Python 3.10.
