Program 1: Add Two Numbers using two variables.

# PROGRAM 1:
# Add two numbers using two variables
# number1
# number2
# sumOfNumbers = Holds the sum of number1 and number2

number1 = 20
number2 = 30

sumOfNumbers = number1 + number2

print('Result: {0} + {1} = {2}'.format(number1, number2, sumOfNumbers))

Result: 20 + 30 = 50

Program 2: Add Two Numbers by numbers inputted by user in console

# PROGRAM 2:
# Add two numbers using two numbers inputted by
# user in the console
# number1 = holds the first number

print('Enter 1st Number:')
number1 = int(input())

print('Enter 2nt Number:')
number2 = int(input())

sumOfNumbers = number1 + number2

print('Sum: {0} + {1} = {2}'.format(number1, number2, sumOfNumbers))

This Program Adds Two Numbers inputted by the user:
Enter 1st Number:

def add_two_numbers(n1, n2):
    sum_of_numbers = n1 + n2
    print('Sum: {0} + {1} = {2}'.format(n1, n2, sum_of_numbers))


number1 = 30
number2 = 40
add_two_numbers(number1, number2)

Sum: 30 + 40 = 70
