Addition Program in Python - Python Tutorial

Addition Program in Python

In this tutorial, we are about build a very simple addition program in Python. We will show how to build a simple program that will add two integer numbers that a user gives us via the terminal or command prompt and then we will return the sum of those two numbers to the user. The program will be accessible to download at the end of the tutorial. Just try to follow along the more you practice writing programs in Python the more you will learn.

Building the Addition Python Program

We will be using sublime text as our text editor to build this program. We will be writing our code using Python 3 syntax.  We will run the code via our terminal or command prompt.

Step 1 - Open Text Editor

Open your text editor so we can write the code for our program.

Step 2 - Save your program

Save your program to your desktop as addition.py

Step 3 - Write Welcome Message For Our Program

Here we will use a simple print statement to welcome our users to our program.

#Write Welcome Message For Our Program

print("Welcome to our addition program")

Step 4 - Get Users First Number

In this step, we will get the users first number using input() and then convert the number to an integer using int() and assign a variable to the object that holds the users first number.

#Get Users First Number

print("Welcome to our addition program")
firstnum = int(input("Give us your first number. "))

Step 5 – Get Users Second Number

In this step, we do the same for the previous step above but we give this user input a different variable.

#Get Users Second Number

print("Welcome to our addition program")
firstnum = int(input("Give us your first number. "))
secondnum = int(input("Give us your second number. "))

Step 6 – Perform The Equation

In this step, we will add the users two numbers together and then assign the sum a variable.

#Perform The Equation

print("Welcome to our addition program")
firstnum = int(input("Give us your first number. "))
secondnum = int(input("Give us your second number. "))
thesum = firstnum + secondnum

Step 7 – Return The Sum To The User

We will return the sum of the user. We will print a string to the user and format the string using a format() method to add our sum into the string.

#Return The Sum To The User

print("Welcome to our addition program")
firstnum = int(input("Give us your first number. "))
secondnum = int(input("Give us your second number. "))
thesum = firstnum + secondnum
print("Your sum is ".format(thesum))

Step 8 – Run The Program

Open your terminal or command prompt and change into your desktop. To run the program, simply type python3 addition.py and press return or enter. The program will ask you to input a number then press return. The program will again prompt you to add your second number again input your number then press return. Now the program will return your sum to you. This is a very simple program in Python.
