即使我在 UI_score 上加了 1，为什么 score_counter 没有更新？

Question

UI_score = 0
player_score = 0
score_counter = str(UI_score) + "-" + str(player_score)
UI_score += 1
print(score_counter)

The score_counter is still giving me 0-0, when it should give me 1-0. Why is this happening?

Answer 1

You update the variable after using the old value, try this instead:

UI_score = 0
player_score = 0
UI_score += 1
score_counter = str(UI_score) + "-" + str(player_score)
print(score_counter)
