Bert is in charge of organizing an event and got the attendees names, locations and confirmations in 3 lists. Assuming he got all data and being Pythonic he used
zipto stitch them together (see template code) but then he sees the output:('Tim', 'DE', False) ('Bob', 'ES', True) ('Julian', 'AUS', True) ('Carmen', 'NL', False) ('Sofia', 'BR', True)
What?! Mike, Kim, and Andre are missing! You heard somebody mention itertools the other day for its power to work with iterators. Maybe it has a convenient way to solve this problem? Check out the module and patch the
get_attendeesfunction for Bert so it returns all names again. For missing data use dashes (-). After the fix Bert should see this output:('Tim', 'DE', False) ('Bob', 'ES', True) ('Julian', 'AUS', True) ('Carmen', 'NL', False) ('Sofia', 'BR', True) ('Mike', 'US', '-') ('Kim', '-', '-') ('Andre', '-', '-')
Good luck, Bert will be grateful if you fix this bug for him! By the way, this won't be the last itertools Bite, it is a power tool you want to become familiar with!
