Python Program to Add Two Numbers

In this post, we learn how to write a python program to add two numbers with a very simple explanation but before writing a program I will explain to you how easy it is to add two numbers in python.

As we know python is a dynamic programming language and it is very much flexible. We can easily add two numbers by using the + operator and print it on the console using the print() function. let’s see how.

# Addition of two integer numbers

print(3+5) # 8
print(10+21) #31

# Addition of two float numbers

print(3.5+21) # 24.5
print(2.1+3.4) # 5.5

Now let’s properly write this program by taking input from the user but before writing a program few programming concepts you have to know:

Source Code

# addition of a and b by taking input from the user
a = float(input('Enter first number : '))
b = float(input('Enter Second number : '))

# take one variable (c) and store the result of a+b.
c = a + b

print(f"sum of {a} and {b} is {c:.2f}")

Output

Enter first number : 4
Enter Second number : 5
sum of 4.0 and 5.0 is 9.00

Now let’s write the above program using a function

But before writing a program few programming concepts you have to know:

Source Code

def addTwo(num1,num2):
    return num1+num2

a = float(input('Enter first number : '))
b = float(input('Enter Second number : '))

# calling a function
c = addTwo(a,b)

print(f"sum of {a} and {b} is {c:.2f}")
