Question

更新抱歉特此完整的错误消息：文件＆＃34; C：\ XXX \ crypto.py＆＃34;，第26行 elif len（chunk）％16！= 0：

IndentationError：期望一个预期的块

这是完整的错误消息。

我的脚本引发IndentationError，你能帮我解决一下吗？

您在以下情况后错过了冒号：

def getKey(password)

你之后也没有：

if len(chunk) == 0:

如果您不想要任何内容，可以添加pass语句作为占位符。如果没有任何内容，Python会给出错误。以下内容适用：

if len(chunk) == 0:
    pass

另外，在以下一行：

def decrypt(key. filename):

这段时间必须是逗号。

在缩进错误上需要一些python帮助
