WITH THE LATEST VERSION OF PYTHON:

A babysitter charges $2.50 an hour until 9:00 PM when the rate drops to $1.75 an hour (the children are in bed). Write a program that accepts a starting time and ending time in hours and minutes and calculates the total babysitting bill. You may assume that the starting and ending times are in a single 24-hour period. Partial hours should be appropriately prorated.
