Python Program to Make a Simple Calculator
Create a simple calculator which can perform basic arithmetic operations like addition, subtraction, multiplication, or division depending upon the user input. Approach :
User chooses 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.
Using functions add(), subtract(), multiply() and divide() evaluate respective operations.
Python3
# Python program for simple calculator# Function to add two numbersdef add(num1, num2): return num1 + num2# Function to subtract two numbersdef subtract(num1, num2): return num1 - num2# Function to multiply two numbersdef multiply(num1, num2): return num1 * num2# Function to divide two numbersdef divide(num1, num2): return num1 / num2print("Please select operation -\n" \ "1. Add\n" \ "2. Subtract\n" \ "3. Multiply\n" \ "4. Divide\n")# Take input from the userselect = int(input("Select operations form 1, 2, 3, 4 :"))number_1 = int(input("Enter first number: "))number_2 = int(input("Enter second number: "))if select == 1: print(number_1, "+", number_2, "=", add(number_1, number_2))elif select == 2: print(number_1, "-", number_2, "=", subtract(number_1, number_2))elif select == 3: print(number_1, "*", number_2, "=", multiply(number_1, number_2))elif select == 4: print(number_1, "/", number_2, "=", divide(number_1, number_2))else: print("Invalid input") |
Output:
Please select operation -
1. Add
2. Subtract
3. Multiply
4. Divide
Select operations form 1, 2, 3, 4 : 1
Enter first number : 15
Enter second number : 14
15 + 14 = 29
