The last bit to complete task 4 is if we find a correct overseas airport code then it needs to print out the whole name of the airport. The video below explains this page.
I have put my data from the text file into a list of lists as you have seen on a previous help page... This means we can index that list as follows interNatList [0][0] will look at the first list entry and the first part of the entry in that list.
[[JFK, John F Kennedy International, 5326, 5486][ORY,Paris-Orly,629,379]]
Below you should be able to see where I have used the data in the list (global list) called interNatList and retrieved the name of the airport from the code entered.
