我的Hang子手遊戲出現錯誤

Question

我正在通過Python的'Invent With Python'來學習Python 2.7。目前正在執行Hang子手章節。

我在過去的3天裏經歷了5次代碼，但是運行代碼時我沒有得到相同的結果。

我的代碼：

import random 

HANGMANPICS = ['''

有人能告訴我是什麼問題 -

1. 按我的理解，我搞亂了縮進。就是不知道在哪裏。

請幫忙。

Python是「空間敏感的」。這樣的代碼

else: 
    missedLetters = missedLetters + guess 

    if len(missedLetters) == len(HANGMANPICS) - 1: 
     displayBoard(HANGMANPICS, missedLetters, correctLetters, secretWord) 
     print 'You have run out of guesses!\nAfter ' + str(len(missedLetters)) + ' missed guesses and ' + str(len(correctLetters)) + ' correct guesses, the word was "' + secretWord + '"' 
     gameIsDone = True 

該塊涉及if子句它上面（if foundAllLetters:）。刪除4個空格，以便else與if guess in secretWord位於同一列。
