g You will write a program that reads in information about customers: which line they go to the back of (1 through 12), at what time (in seconds) they enter that line, and the number of items they have, and determines at what time each customer will check out.

Consider a list of full names formatted “firstname lastname”, like ["jules verne", "alexandre dumas", "maurice druon"]. write a list comprehension that produces a list with the full names in the format “lastname, firstname”. the resulting list should look like ['verne, jules', 'dumas, alexandre', 'druon, maurice']. the simplest solution may involve a nested comprehension: [ …. for … in [ … for … in … ]].
