在python3中,所有的类都是新式类,也就是如果一个类没有继承任何父类,那么它就默认继承object类。 所以我们可以在定义类时使类继承object类,这样可以使我们的代码兼容Python2。 classParent1:passprint(Parent1.__bases__)# 默认继承object类# (<class 'object'>,)classParent1(object):# 手动继承object类,使...

The wrapper function uses *args and **kwargs to pass on arguments to the decorated function. If you want your decorator to also take arguments, then you need to nest the wrapper function inside another function. In this case, you usually end up with three return statements. You can ...
The *args and **kwargs is an approach to pass multiple arguments to a Python function. They allow to pass a variable number of arguments to a function. However, please note it is not necessary to name the variables as *args or **kwargs only. Only the * is important. We could also...
