Getting a string from a list in a list

[Magnie]

I am making a game, and I'm wondering how I can get a string( /element ) out of a list in a list.

players = [["Magnie","apassword"],["Test","apassword"]]
if username == players[0[0]] and password == players[0[1]]:
    print "Welcome back,",username+"!"
 

Something like that? ( That's not the real code, just something that I want. ;) )

Almost correct, it's players[i][j] instead of players[[i]j] (where i and j are of course the actual values you want to use, or a variable holding that value).

One way of doing this is to convert the 2d list into a dictionary via {}.update()

players_dict = {}
players_dict.update(players)
if username in players_dict: 
    if password == players_dict[username]:
        print "Welcome back,",username+"!"

Another (shorter, but messier) way:

lst = zip(*players)[0]
if username in lst:
    print "Welcome back" if password == players[lst.index(username)][1] else "Wrong Password"

Yarr: Ohh, thanks! I thought that if a list is inside a list it would make more sense to do it the other way. :P Thanks again!
