My code keeps asking me to give a player's name, even if i choose to NOT add another player.

# TODO Create an empty list to maintain the player names

players = []
# TODO Ask the user if they'd like to add players to the list.

add_player = input("Would you like to add a player? yes/no")
# If the user answers "Yes", let them type in a name and add it to the list.

# If the user answers "No", print out the team 'roster'
while add_player.lower() == "yes":
    name = input("Enter the name of the player to add to the team: ")
    players.append(name)
    add_players = input("Would you like to add another player? yes/no ")



# TODO print the number of players on the team

print("There are {} players on the team.".format(len(players)))


# TODO Print the player number and the player name
# The player number should start at the number one
player_number = 1
for player in players:
    print(("Player {}: {}".format(player_number, player)))
    player_number += 1

# TODO Select a goalkeeper from the above roster
keeper = input("Please select the goal keeper by selecting player number. (1-{})".format(len(players)))
keeper = int(keeper)
# TODO Print the goal keeper's name

print("Great!! The goalkeeper for the game will be {}".format(players[keeper - 1]))
# Remember that lists use a zero based index
