Calculator in Python

Create a simple calculator program that will display a menu, which contains four basic mathematical operations such as Addition, Subtraction, Multiplication, and Division. The user selects an operator from the menu and then, provides value, and the program will perform the computation based on the operator selected by the user and display the result on the screen.
