1、修改机票

 

代码：

import sys
def reschedule(origins, changes):
    tickets = {}
    new_tickets = {}
    for origin in origins:
        airline, seat, name = origin.split(',')
        tickets[(airline, seat)] = name
        new_tickets[name] = (airline, seat)

    for change in changes:
        old_airline, old_seat, new_airline, new_seat = change.split(',')
        name2 = tickets[(old_airline, old_seat)]
        new_tickets.pop(name2)
        new_tickets[name2] = (new_airline, new_seat)
    print(new_tickets)

if __name__=="__main__":
    # input=
    '''
