Program to find the sum of two numbers using functions in Python

The addition program in python using function to find the sum of two numbers is as follows:

 

# Owner : TutorialsInhand Author : Devjeet Roy

# Function Body
def add_numbers(n1,n2):
    sum_of_numbers = n1 + n2
    return sum_of_numbers

# Main Body
if __name__ == "__main__":
    a = float(input("Enter first number: ")).strip()
    b = float(input("Enter second number: ")).strip()
    addition = add_numbers(a,b)
    print("The sum is",addition)

The output of the program to add two numbers using function in python is as follows:

 

PS C:\Users\DEVJEET\Desktop\tutorialsInHand> python code.py
Enter first number: 23
Enter second number: 12
The sum is 35.0

Few important tips about the program

1. def keyword is used to define a function.

2. The variables n1 and n2 are called the parameters to a function.

3. The value which are passed to the parameters are known as arguments.

4. if __name__ == "__main__" is used to tell the python interpreter that our program starts from there. It is like the main() function in C or public static void main(String args[]) in Java.
