Menu Driven Program in Python using while loop

A menu-driven program to find the area of a circle, square, and rectangle in python.
In this post we will make a menu-driven program using a while loop and simple if-else statements for the following operations:

1. Area of Circle
2. Area of Rectangle
3. Area of square
4. Exit

while True:
    print("Menu Driven Program")
    print("1.Area of Circle")
    print("2.Area of Rectangle")
    print("3.Area of Square")    
    print("4.Exit")
    choice=int(input("Enter your choice:"))
    if choice==1:
        radius=int(input("Enter radius of Circle:"))
        print("Area of Circle",3.14*radius*radius)
    
    elif choice==2:
        length=int(input("Enter length of Rectangle:"))
        breadth=int(input("Enter breadth of Rectangle:"))
        print("Area of Rectangle:",length*breadth)
    
    elif choice==3:
        side=int(input("Enter side of Square:"))
        print("Area:",side*side)
    elif choice==4:
        break
    else:
        print("Wrong Choice")
    repeat=input("Do you want to continue? (y/n)")
    if repeat=='n'or repeat=='N':
        break
        

Output:

Menu Driven Program
1. Area of Circle
2. Area of Rectangle
3. Area of Square
4. Exit
Enter your choice:3
Enter the side of Square:5
Area: 25

Quick algorithm:

• Print the menu on the screen.
• Input the choice from the user.
• According to their choice, display the area using the if-else statement.

Menu Driven Program for Class 12th Students [CBSE BOARD]

We will make a program that helps us calculate the area of shapes according to the user's choice. The user will decide whether he wants to get the area of a square or a circle, depending on his/her choice. 

We will make this program using an infinite while loop which will terminate as soon as users choose the option to exit. We will store his choice in a variable, which tells us about his choice so that we can make our if-else statements.Then we ensure that we cover all the conditions that our menu provides. However, there will be another case when the user provides input which is not available in our menu. 
For example, you go to Domino and order momos which is unavailable on their menu. So, they will tell you "Wrong choice" and order something else shown on their menu. Hence we will add an else statement that will print the wrong choice.

Menu Driven Program in Python using functions

In this program, we will create a python program for class 12 in which we will calculate the area of different shapes like circles, squares, and rectangles using functions.

def circle(radius):
    print("Area of Circle",3.14*radius*radius)

def rectangle(length,breadth):
    print("Area of Rectangle:",length*breadth)
    
def square(side):
    print("Area:",side*side)

while True:
    print("Menu Driven Program")
    print("1.Area of Circle")
    print("2.Area of Rectangle")
    print("3.Area of Square")    
    print("4.Exit")
    choice=int(input("Enter your choice:"))


    if choice==1:
        radius=int(input("Enter radius of Circle:"))
        circle(radius)


    elif choice==2:
        length=int(input("Enter length of Rectangle:"))
        breadth=int(input("Enter breadth of Rectangle:"))
        rectangle(length,breadth)
    
    elif choice==3:
        side=int(input("Enter side of Square:"))
        square(side)


    elif choice==4:
        break
    else:
        print("Wrong Choice")

Output:

Enter your choice:1
Enter radius of Circle:5
Area of Circle 78.5

This Menu-driven program in python using functions is essential for class 12th students. One question about this program can come from the CBSE board, so prepare well for it. If you have any doubt, let me know in the comment section.
We can also call this program a python menu loop because we will display the menu in a loop until the user wants to exit.

Questions Related to this Program

Explain a menu-driven program with an example?
Menu-driven program using if-else, which will perform operations according to the user's choice. Here are examples of menu-driven programs.

1. Menu-driven program to calculate the area/perimeter of different shapes.
2. Menu-driven program to perform simple arithmetic operations (create a simple calculator) like adding two numbers in python and subtraction.

How do you exit a menu-driven program?
We have to use the break statement to exit from the loop. When users want to leave the loop, They will choose the option to exit, and in that "if condition," we will write a break statement.
