Help Defining Global Names

Question

My Code:

def A():
    a = \'A\'

    print a

    return

def B():

    print a + \' in B\'

    return

When B() is entered into the interpeter

Answer 1

def A():
    global a
    a = 'A'
    print a

def B():
    global a
    print a + ' in B'

A()
B()

this prints:

A
A in B

BTW: You never need a plain "return" at the end of a function.
