      In this article, we will learn how to create a simple calculator in Python.

      In our calculator, basic operations like addition, subtraction, multiplication, and division. You need to have prior knowledge about functions to clearly understand this program. Once you get the idea, you can add many other features to the calculator.

      #python program for simple calculator
      
      #addition function
      def add(n1, n2):
          return (n1 + n2)
      
      #subtraction function
      def sub(n1, n2):
          return (n1 - n2)
      
      #multiplication function
      def mul(n1, n2):
          return (n1 * n2)
      
      #division function
      def div(n1, n2):
          return (n1 / n2)
      
      print("****SIMPLE CALCULATOR****")
      print("1. Add\n2. Subtract\n3. Multiply\n4. Divide\n")
      
      #take input from user
      choice = int(input("Select operations form 1, 2, 3, 4 : "))
      
      num1 = int(input("Enter first number: "))
      num2 = int(input("Enter second number: "))
      
      if choice==1:
          print(add(num1, num2))
      elif choice==2:
          print(sub(num1, num2))
      elif choice==3:
          print(mul(num1, num2))
      elif choice==4:
          print(div(num1, num2))
      else:
          print("Invalid input")
      ****SIMPLE CALCULATOR****
      1. Add
      2. Subtract
      3. Multiply
      4. Divide
      
      Select operations form 1, 2, 3, 4 : 3
      Enter first number: 3
      Enter second number: 7
