需要對indentationerror

Question

更新對不起特此完整的錯誤消息，一些Python幫助： 文件 「C：\ XXX \ crypto.py」 26行 ELIF LEN（塊）％16 = 0：

IndentationError：預期預期的塊

這是完整的錯誤消息。

我的腳本引發了一個IndentationError，你能幫我解決嗎？

Answer 1

你缺少一個冒號後：

def getKey(password) 

你也沒有什麼後：

if len(chunk) == 0: 

如果你不想要的東西在那裏，你可以添加一個pass聲明作爲佔位符。如果沒有任何東西，Python會給出錯誤。下面的工作：

if len(chunk) == 0: 
    pass 

此外，在下面一行：

def decrypt(key. filename): 

週期必須是一個逗號。
