Constant PYTHON_STR_METHODS 

pub const PYTHON_STR_METHODS: &'static [&'static str];

Python str instance methods that an enum member name can shadow.

StrEnum inherits from str, so variant names that match str instance methods (e.g., Title → title) shadow the inherited method and trigger mypy [assignment] errors at the class body. This constant lists all such methods that must be escaped with a trailing underscore when used as enum member names (e.g., title_).
