__dict__

• 以字典形式返回对象中封装的内容

class C:

    def __init__(self, name):
        self.name = name

obj = C('python')
print(obj.__dict__)
print(C.__dict__)

输出结果：

　　{'name': 'python'}

　　{'__module__': '__main__', '__init__': <function C.__init__ at 0x00000000022999D8>, '__dict__': <attribute '__dict__' of 'C' objects>, '__weakref__': <attribute '__weakref__' of 'C' objects>, '__doc__': None}
