[issue35954] Incoherent type conversion in configparser

[Rémi Lapeyre]

Rémi Lapeyre <remi.lapeyre at henki.fr> added the comment:

Other methods validate explicitly their arguments with _validate_value_types for example.

Here it raises KeyError which does not seem to be the appropriate exception. ConfigParser implementing the mapping protocol it seems weird to me to have

    >>> a = 123
    >>> config[a] = {}
    >>> config[a]
    KeyError: 123

I would have prefered a TypeError to be raised on __setitem__ but this is now documented behavior.
