計算機科學項目的編碼拼圖

Question

我正在做一個計算機科學項目的編碼拼圖。

我做得不錯，直到我遇到縮進塊錯誤。它是在線63.

任何幫助將是輝煌！

下面是代碼：

#check to see if letters used 
while True: 
    try: 
     x=words.index(answer1) 
     answer2=raw_input('Now please type the letter you wish to replace it with') 
     words=words.replace(answer1,answer2) 
    except ValueError: 
     print "there is an error using this letter/symbol, try again" 
     break 
    answer2=raw_input('Now please type the letter you wish to replace it with') 
    words=words.replace(answer1,answer2) 
    if words==check: 
     print"Congratulations" 
    else: 
     #routine to delete a previous guess 


     #find #if answer1=="+": 
       #if answer2=="C" 
       # +=C 
     #words2=words.replace(answer1,answer2)   

Answer 1

的問題是與else塊。在Python中，縮進很重要，所以沒有塊可以完全空白。如果else聲明的目的是什麼都不做，寫

else: 
    pass
