iPython tab completion of method variable

[sixteenornumber]

is there any way to get iPython to recognize the type of "each" in B.printBarList().  for example I want to use tab-complete in iPython so I type "each." but it doesn't know the type.  

# A.py
class A:
    
    def __init__(self):
        self._foo = "FOO"

    def getFoo(self):
        return self._foo

# B.py
from A import A
class B:

    def createBarList(self):
        '''create 10 instances of A in barList'''
        barList = []
        for i in range(10):
            barList.append(A())
        return barList

    def printBarList(self, barList):
        '''
        Itter over each A in barList and print each
        ***MY QUESTION*** the "each" in the loop below
        '''
        for each in barList:
            print(each.foo)

if __name__ == "__main__":

    b = b()
    barList = b.createBarList()
    b.printBarList()

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
