Currently docstring written for even property.setter is ignored in help as inspect.getdoc only inspects property.fget [0] for docstrings. I feel docs for setter could also be included. The docs also indicate the same at https://docs.python.org/3.6/library/functions.html#property . In the absence of docs maybe the signature for getter and setter could be included as per this proposal.

class Foo:
    @property
    def bar(self) -> int:
        '''Bar docs for property'''
        return 42

    @bar.setter
    def bar(self, value: int) -> None:
        '''Bar docs for setter'''
        pass

help(Foo.bar)
