python django randomly select value excluding one

I have a view like:

try:
    check_winner = Winner.objects.get(phone_no=9899889988)
    if check_winer:
        winner = random.choice(player_list)
    else:
        winner = winner
except Winner.DoesNotExist:
    pass

Here what I want is if check_winner exists then again randomly select the winner from player but excluding that check_winner

How can I exclude some value from random list of players
