Put the players in a list.
player_list = [player1, player2, player3... ]
So if you want to get to player1 data, you use player_list[0][0...2], 
which would be the same as player1[0...2].

If you then want to do something to every player, you could do:

for player in player_list:
    do something

Functions return values. To keep the return value, you simply have to 
assign it to a variable:

result = choose_player(3)

And then you can do whatever you want with result. Bear in mind that 
result and player3[3] are *not* the same thing, they only have the same 
value.


HTH!
