Python decorator使用wrapps，但名称仍在更改

Question

我有下面的错误处理程序（实际上是旁路程序）装饰程序-

import functools

def exception_safe(*args):
        ErrList = tuple(args)
        def decorator(f):
                @functools.wraps(f)
                def wrapper(*args, **kwargs):
                        if ErrList:
                                try:
                                        result = f(*args, **kwargs)
                                        print(f'No error!')
                                        return result 
                                except ErrList as err:
                                        print(f'got error!')
                        else:
                                try:
                                        result = f(*args, **kwargs)
                                        print(f'No error!')
                                        return result 
                                except Exception as err:
                                        print(f'got error!')
                return wrapper
        return decorator

即使我仍然从pytests得到下一个断言错误，告诉我函数名是decorator：

为什么会这样？我什么都试过了

exception_safe需要给定参数，即使没有：

@exception_safe()
def function():
