In this Article, We will see How to add two numbers in Python.
Example:

Input:  number1 = 12, number2 = 13
Output: 25

Input: number1 = 10, number2 = 40
Output: 50

Now, let’s see the different ways to code:

Code 1:

# Code - 1
# Given input numbers
number_1 = 12
number_2 = 13

# perform addition
print(number_1 + number_2)

Output:

25

Code 2:

# Code - 2
# Main Code
if __name__ == "__main__" :

    # Given input numbers
    number_1 = 12
    number_2 = 13

    # perform addition
    print(number_1 + number_2)

Output:

25

Code 3:

# Code - 3

# Main Code
if __name__ == "__main__" :

    # take string input from user
    number_1 = input("Enter 1st Number: ")
    number_2 = input("Enter 2nd Number: ")
 
    # type casting into integer
    number_1 = int(number_1)
    number_2 = int(number_2)

    # perform addition
    print(number_1 + number_2)

Output:

Enter 1st Number: 10
Enter 2nd Number: 40
50

Code 4:

# Code - 4

# Main Code
if __name__ == "__main__" :

    # take string input from user
    number_1 = input("Enter 1st Number: ")
    number_2 = input("Enter 2nd Number: ")
 
    # type casting into integer 
    # and then perform addition
    print(int(number_1) + int(number_2))

Output:

Enter 1st Number: 10
Enter 2nd Number: 40
50

Code 5:

# Code - 5
# Main Code
if __name__ == "__main__" :

    # take integer input from user
    number_1 = int(input("Enter 1st Number: "))
    number_2 = int(input("Enter 2nd Number: "))

    # perform addition
    print(number_1 + number_2)

Output:

Enter 1st Number: 10
Enter 2nd Number: 40
50

Code 6: By creating user-defined function.

# Code - 6

# Create a user-defined function
# For adding two numbers
def sum_2_numbers(number_1, number_2) :

    # return addition of 2 numbers
    return number_1 + number_2

# Main Code
if __name__ == "__main__" :

    # take integer input from user
    number_1 = int(input("Enter 1st Number: "))
    number_2 = int(input("Enter 2nd Number: "))

    # Function calling
    print(sum_2_numbers(number_1, number_2))

Output:

Enter 1st Number: 10
Enter 2nd Number: 40
50

Code 7: By using Lambda function.

# Code - 7

# Create an anonymous/lambda function
# For adding two numbers
sum_2_numbers = lambda  number_1, number_2 : number_1 + number_2

# Main Code
if __name__ == "__main__" :

    # take integer input from user
    number_1 = int(input("Enter 1st Number: "))
    number_2 = int(input("Enter 2nd Number: "))

    # Function calling
    print(sum_2_numbers(number_1, number_2))

Output:

Enter 1st Number: 10
Enter 2nd Number: 40
50
