Python-Vikend

• The following invocations of your program must work

  • ./book_flight.py --date 2017-10-13 --from BCN --to DUB --one-way
  • ./book_flight.py --date 2017-10-13 --from LHR --to DXB --return 5
  • ./book_flight.py --date 2017-10-13 --from NRT --to SYD --cheapest
  • ./book_flight.py --date 2017-10-13 --from CPH --to MIA --shortest

  where --one-way (make this the default option) indicates need of flight only to location and --return 5 should book flight with passenger staying 5 nights in destination,

  --cheapest (default) will book the cheapest flight and --shortest will work similarly

  The program will output a PNR number which serves as confirmation of booking

  The --from and --to parameters only need to support airport IATA codes
