4-9 Python自省机制

class Person:
    name = "person"

per = Person()
print(per.__dict__)
print(Person.__dict__)

{}
{'__doc__': None, '__weakref__': <attribute '__weakref__' of 'Person' objects>, '__module__': '__main__', 'name': 'person', '__dict__': <attribute '__dict__' of 'Person' objects>}

通过dict来查类的属性结构
