get_property_name

get_property_name(string: str) -> str

Converts a "camelCased" attribute/property name, a name which conflicts with a python keyword, or an otherwise non-compatible string to a PEP-8 compliant property name.

Examples:

>>> print(get_property_name("theBirdsAndTheBees"))
the_birds_and_the_bees

>>> print(get_property_name("theBirdsAndTheBEEs"))
the_birds_and_the_bees

>>> print(get_property_name("theBirdsAndTheBEEsEs"))
the_birds_and_the_be_es_es

>>> print(get_property_name("FYIThisIsAnAcronym"))
fyi_this_is_an_acronym

>>> print(get_property_name("in"))

>>> print(get_property_name("id"))

>>> print(get_property_name("one2one"))  # No change needed
