New submission from Aaron Koch <aaronkoc...@yahoo.com>:
Documentation: https://docs.python.org/3/library/enum.html#creating-an-enum Current behavior: SomeEnum[name] is used to construct an enum by name SomeEnum(value) is used to construct an enum by value Problem: As a user of enums, it is difficult to remember the mapping between parenthesis/square brackets and construct from name/construct from value. Suggestion: Add two class methods to Enum @classmethod def from_name(cls, name): return cls[name] @classmethod def from_value(cls, value): return cls(value) Benefits: This is an additive change only, it doesn't change any behavior of the Enum class, so there are no backwards compatibility issues. Adding these aliases to the Enum class would allow readers and writers of enums to interact with them more fluently and with less trips to the documentation. Using these aliases would make it easier to write the code you intended and to spot bugs that might arise from the incorrect use of from_name or from_value. ---------- messages: 403936 nosy: aekoch priority: normal severity: normal status: open title: Enum add "from_name" and "from_value" class methods type: enhancement _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45473> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
