iPython tab completion of method variable

[sixteenornumber]

I found my answer.  as of python 3.5 

import typing

def foo(bar: int) --> int:
    return bar**2

in ipython when you enter,  "foo()" it wll prompt with "bar: int returns int". this also works with class types.

class Baz:
    def __init__(self):
        pass

def foo(bar: Baz) --> None:
    pass
