Hi, I'm getting this error.
Traceback (most recent call last):

run_battle(player_team, ai_team)

raise IndexError('Cannot choose from an empty sequence')
IndexError: Cannot choose from an empty sequence
I have added the code below. Can someone please help, my submission is tmrw. The error is very random too, it randomly breaks whenever I run the game. sometimes it works.
