Class is an object and can be decorated like a function

Decorator for class. py

def deco (obj):    print (' ====== ', obj)    obj.x=1    obj.y=2    obj.z=3    return obj# @deco  #test =deco ( Test) # DEF Test (): #     print (' Test function run ')
#运行了装饰器所以打印了装饰器里面的print内容 @deco #Foo =deco (Foo)
#======class Foo:    Pass
#打印类的字典 where the XYZ attribute is defined in the adorner function as print (foo.__dict__) #{' __doc__ ': None, ' Z ': 3, ' Y ': 2, ' __dict__ ': <attribute ' __dict__ ' of ' foo ' objects>, ' __weakref__ ': <attribute ' __weakref__ ' of ' foo ' objects>, ' x ': 1, ' __module__ ': ' __main__ '}

This decorator is to pass the class as an argument to the function Deco and then assign the return value to Foo, and in the adorner function you can define the properties of the corresponding class.
