Basic Calculator in Python

A simple calculator program that will display a menu which contains

four basic mathematics operators like addition, subtraction, multiplication and

division. The user selects an operator from the menu and then provide value and 

the program will perform the computation based on the operator selected by the 

user and display the result on the screen using Python programming language.
