Python without Def function Problem Statement Define and implement a function time_delta that takes two string parameters (time1 and time2) and returns the difference between them (as a string). You may assume that the second time will always be after the first time, both times will always be on the same date, and military time will be used (no a.m. or p.m.). Examples time_delta(04:15:36, 16:35:27) ➞ (12:19:51) time_delta(02:06:05, 06:09:10) ➞ (04:03:05) Sample Input 1 "04:15:36" "16:35:27" Sample Output 1 "12:19:51"
