''' Repeating for all players

Now that you’ve worked out how to add players to teams, you need to keep going until all of the players have been allocated to one of the teams.
Using a loop, and making sure to not try to pick a player from an empty list,
finish off this program to split the players into two teams, teamA and teamB.
Make sure to print the two teams at the end of the program to make sure it’s worked, and share your code in the comments. '''
