Python Program to Make a Simple Calculator - jack_sparrow007 - Oct-19-2018 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 following Python programming topics: Python Functions Python Function Arguments Python User-defined Functions Source Code: Simple Caculator by Making Functions # Program make a simple calculator that can add, subtract, multiply and divide using functions # 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") # Take input from the user choice = input("Enter choice(1/2/3/4):") num1 = int(input("Enter first number: ")) num2 = int(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)) else: print("Invalid input")Output In this program, we ask the user to choose the desired operation. Options 1, 2, 3 and 4 are valid. Two numbers are taken and an if...elif...else branching is used to execute a particular section. User-defined functions add(), subtract(), multiply() and divide() evaluate respective operations.Good Luck RE: Python Program to Make a Simple Calculator - buran - Oct-19-2018 Welcome to the forum.
