The function lent does not have a return statement, so it defaults to return None

def lent(length):
    print("Added! list has {} items".format(length))
    return None  # <-- default

        # The last print statement
        print(lent(len(items_list)))
        # effectively becomes
        print(None)

Two options

:point_right: Have lent return the string instead of print it locally

:point_right: change the last statement into a call to lent instead of printing the return value.

Post back if you have more questions. Good luck!!
