How to make a calculator using python ?

 It's a good idea to make a calculator using python. It is very easy and useful while in the online class or online math exam (joking). Before That let us know a little about all IDE(Integrated development environment). Don't get confused here by the name. It is simply a software application that provides complete facilities to computer programmers for software development or program development. 

So we are here trying to make a program that will give us a sum of 2 numbers, Subtract between 2 numbers, Multiplying 2 numbers, and Divide 2 numbers. 

Now let's start programming…..

Using functions add(), subtract(), multiply() and divide() evaluate respective operations.

Code:  

#Function to Add

def add(num1, num2):

    return num1 + num2

#Function to subtract




def subtract(num1, num2):

    return num1 - num2

  

#Function to multiply

def multiply(num1, num2):

    return num1 * num2

 #Function to Divide

def divide(num1, num2):

    return num1 / num2

  

print("Please select operation -\n" \

        "1. Add\n" \

        "2. Subtract\n" \

        "3. Multiply\n" \

        "4. Divide\n")

  

  




select = 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
    

I hope all those who were reading have understood this concept very well.....
