Question

In Python, write a function def printAirlineFlightNums(airD): that will print out the names of all of the airlines along with the flight numbers for all flights for that airline.

flightsD={"Delta":{1102:[["IND",1850],["MDW",1955]],
1096:[["PHX",900],["MDW",1255]],
1445:[["ATL",1135],["LAX",1810]],
1776:[["PHL",1350],["RAP",1610]],
1226:[["PHX",950],["MDW",1345]],
1885:[["ATL",1305],["LAX",2000]],
1009:[["MDW",1850],["IND",1955]],
9001:[["MDW",2145],["IND",2255]]},
"Southwestern":{1111:[["SAT",430],["MDW",825]],
2121:[["MDW",430],["SAT",825]],
4335:[["PHX",450],["MDW",745]],
1102:[["MDW",1100],["PHX",1450]]},
"American":{7765:[["IND",1850],["CHA",2105]],
2133:[["BNA",900],["IND",1115]],
3321:[["HOU",1335],["ATL",1615]],
2100:[["BNA",900],["IND",1115]],
4311:[["HOU",905],["ATL",1255]],
5577:[["ATL",1100],["HOU",1350]],
1102:[["BNA",1100],["HOU",1450]]}}
