Explanation:

Python Program to Make a Simple Calculator

In this example you will learn to create a simple calculator that can add, subtract, multiply or divide depending upon the input from the user.

To understand this example, you should have the knowledge of the following Python programming topics:

Python Functions

Python Function Arguments

Python User-defined Functions

Example: Simple Calculator by Using Functions

# Program make a simple calculator # This function adds two numbers def add(x, y): return x + y # This function subtracts two numbers def subtract(x, y): return x - y # This function multiplies two numbers def multiply(x, y): return x * y # This function divides two numbers def divide(x, y): return x / y print("Select operation.") print("1.Add") print("2.Subtract") print("3.Multiply") print("4.Divide") while True: # Take input from the user choice = input("Enter choice(1/2/3/4): ") # Check if choice is one of the four options if choice in ('1', '2', '3', '4'): num1 = float(input("Enter first number: ")) num2 = float(input("Enter second number: ")) if choice == '1': print(num1, "+", num2, "=", add(num1, num2)) elif choice == '2': print(num1, "-", num2, "=", subtract(num1, num2)) elif choice == '3': print(num1, "*", num2, "=", multiply(num1, num2)) elif choice == '4': print(num1, "/", num2, "=", divide(num1, num2)) break else: print("Invalid Input")

Output

Select operation. 1.Add 2.Subtract 3.Multiply 4.Divide Enter choice(1/2/3/4): 3 Enter first number: 15 Enter second number: 14 15.0 * 14.0 = 210.0
