我剛開始學習 python，目前正在嘗試使用 tkinter 制作經典的“劊子手”游戲。邊做邊學，你懂的
請參閱下面的代碼。當然遠非完美，但總體上有效 - 然而，任何一般反饋都值得贊賞。
現在我被卡住了（并嘗試了幾個小時..）：在完全猜出一個單詞后，它會自動顯示下一個單詞（通常來自隨機串列，但我在這里洗掉了它）。我希望最后一句話在螢屏上停留幾秒鐘，但無論我做什么都不會發生這種情況。我玩弄after了小部件的方法和time.sleep現在。但是沒有效果。
主要問題：當猜出一個單詞的最后一個字母時，它不會顯示最后一個字母而是直接轉到新單詞。
問題似乎出在new_word()我創建的函式上，因為當我洗掉它時，至少會顯示最后一個字母（但游戲當然不會向前推進）。
真的讓我發瘋，因為我找不到這種行為背后的邏輯。我希望有人可以看看并告訴我出了什么問題。

uj5u.com熱心網友回復：
在time.sleep()完全掛程式。這可能就是原因。
因此，創建一個具有類似名稱的新函式，newword_start()并在其中添加以下兩件事：
time.sleep(1)
new_word()
然后在代碼的最開始，添加import threading as th.
然后在make_guess()函式中， after if '_' not in letters...，newword_start()像這樣呼叫函式：
th.Thread(target=newword_start).start()
所以最終的代碼將是：
# Other modules
import threading as th
import time
# Your code
def newword_start():
time.sleep(1)
new_word()
class Player:
# Your code
def make_guess(self, letter):
# Your code again
if '_' not in letters: # Won?
self.score = 1
th.Thread(target=newword_start).start()
# Rest all code
