First to Five

Lesson 37 of 41 in Coddy's Make Games with Pygame course.

The first player to 5 points wins. Keep the winner's name in a variable that starts as None, Python's value for "nothing yet":

winner = None

if left_score == 5:
    winner = "Left player wins!"
elif right_score == 5:
    winner = "Right player wins!"

Test it with winner is None or winner is not None. Once someone has won, the ball keeps waiting: Space serves only while winner is None.

Show the winner centred at (300, 120), in place of the serve message.

Challenge

Medium

End the match at five points.

Before the loop, set winner = None. After the scoring, set it to "Left player wins!" when left_score == 5, or "Right player wins!" when right_score == 5.
Space serves only while winner is None.
Show the winner centred at (300, 120) instead of Press Space to serve.

Press Play: at five points the winner shows. Then Check.
