sys.exit("Error: Please provide exactly two numbers as arguments") else: (num1, num2) = sys.argv[1:] total = int(num1) + int(num2) print("{} + {} = {}".format(num1, num2, total)) $ echo $? File "./sum_of_two_numbers.py", line 9, in <module> total = int(num1) + int(num2) $ echo $? if len(sys.argv) < 2:

In the program below, we've used the + operator to add two numbers. Example 1: Add Two Numbers # This program adds two numbers num1 = 1.5 num2 = 6.3 # Add two numbers sum = num1 + num2 # Display the sum print('The sum of {0} and {1} is {2}'.format(num1, num2, sum)) Output. The sum of 1.5 and 6.3 is 7.8. The program below calculates the sum of ...
