[英]Has key check for a Class
I have a an if check that uses has.key:我有一个使用 has.key 的 if 检查:
if self.has_key(observer.key):
and i am trying to replace it to use the in
keyword.我正在尝试将其替换为使用
in
关键字。
I have tried doing:我试过做:
if observer.key in self:
#
if observer.key in self.__dict__:
But neither of them work returning:但他们都没有返回工作:
E TypeError: argument of type 'Observers' is not iterable
The class had a has_key method deep inside, which did this functionality but i assume pycharm though it was the builtin method: class 内部有一个 has_key 方法,它执行此功能,但我假设 pycharm 虽然它是内置方法:
def has_key(self, key):
return key in self.keys
