    Currently, inspect.signature doesn't support all callables from the operator module, e.g. operator.attrgetter:

    >>> import inspect
>>> import operator
>>> inspect.signature(operator.attrgetter("spam"))
ValueError: callable operator.attrgetter('is_host') is not supported by signature

    Support for this could be added either directly to inspect.signature or by adding __signature__ attributes to operator's classes.

    Looks like this is fixed in Python 3.12:

    >>> import inspect
>>> import operator
>>> inspect.signature(operator.attrgetter("spam"))
<Signature (*args, **kwargs)>

    Specifically, it's fixed in the unreleased 3.12.3 (currently available in Debian unstable), probably by #116198
