Create a Program to Implement Function Overloading in Python Assignment Solution

Instructions

Objective

Write a program to implement function overloading in python language.

Requirements and Specifications

Complete one function at a time by changing the return statement and see the asserts pass for that function complete functions that return a string or a number value with the return statement instead of printing a value.
