Python Programming - Multiples Less Than A Number

Multiples not less than a number
Question 1
Write a Python 3 program that calculates the nearest multiple of a number that is not less than a factor. Your program should get two arguments from the command line and pass them to a function called get_nearest_multiple() -- this part has been written for you. You need to write a function get_nearest_multiple() that takes two integer arguments, in the following order: a minimum number and a factor. Your function should return an integer that is the smallest multiple of the factor that is not less than the minimum number. You can assume that the minimum number will not be negative and that the factor will be positive.
Question 2 (out of 3)
Write a paragraph (minimum length: one sentence) that explains what sys.argv is and where its contents come from. Be sure to mention what the first item in sys.argv is.
Question 3 (out of 3)
Write a paragraph (you will probably need more than one sentence) that explains what the function parse_args() does and how it does it.
