They’re all listed in the keyword module:
>>> import keyword
>>> keyword.kwlist
['False', 'None', 'True', 'and', 'as', 'assert', 'async', 'await',
'break', 'class', 'continue', 'def', 'del', 'elif', 'else',
'except', 'finally', 'for', 'from', 'global', 'if', 'import',
'in', 'is', 'lambda', 'nonlocal', 'not', 'or', 'pass', 'raise',
'return', 'try', 'while', 'with', 'yield']
(output as of Python 3.11)
From the keyword.kwlist doc:
Sequence containing all the keywords defined for the interpreter. If any keywords are defined to only be active when particular
__future__statements are in effect, these will be included as well.
