> Python doesn't have a standards document. It has a reference implementation that defines the language. That's not quite strictly true, Python does have a documented "Language Reference": https://docs.python.org/3/reference/index.html https://docs.python.org/3/reference/index.html If there is a contradiction between the Language Reference and CPython then one, or both, of them needs to be updated and it's treated on a case by case basis. If an alternative Python implementation follows the Language Reference but chooses different details outside it, that doesn't stop it from being "Python". Of course practically speaking most alternative implementations are incentivized to closely follow CPython.
