面向对象5 类特殊成员之 dict 自定义form框架时会用到

class Foo:
    def __init__(self):
        self.name = "TOM"
    
    def haha(self):
        pass
  
r = Foo()
print(r.__dict__)    输出对象中保存的值：{'name': 'TOM'}
print(Foo.__dict__)  输出类中所有内容：{'__module__': '__main__', '__init__': <function Foo.__init__ at 0x10ff261e0>, 'haha': <function Foo.haha at 0x10ff26268>, '__dict__': <attribute '__dict__' of 'Foo' objects>, '__weakref__': <attribute '__weakref__' of 'Foo' objects>, '__doc__': None}
