今天，出现了一些意想不到的行为。当我写这个时：
class ErrorPost(object):
def __init__(self, message):
self.message = "[Error]" + message
print(self.message)
del self
class ErrorLog(ErrorPost):
def __init__(self, message):
super().__init__(message)
del self
此代码在创建 ErrorLog 对象时引发错误：
TypeError: 'type' object is not subscriptable
为什么是这样？我不是在操作任何东西的类型，也不是试图将一个对象变成另一种类型，比如 int。发生了什么事，这里？
我可以发布的代码数量有限，抱歉。
