Where Are Instance Properties Stored
Where Are Instance Properties Stored?
✍: FYIcenter.com
Instance properties are stored in a built-in property called "__dict__" in each instance object.
The "__dict__" property is inherited from the base class "object" and managed by the Python engine.
If you ever forget what instance properties are associated with a specific instance object, you can always look at the content of the built-in property "__dict__". For example:
>>> class user(): ... nextID = 1 ... def __init__(self,name="Joe",age=25): ... self.id = user.nextID ... self.name = name ... self.age = age ... user.nextID = user.nextID + 1 ... >>> x = user() >>> x.remark = "Smart guy!" >>> x.__dict__ {'id': 6, 'name': 'Joe', 'age': 25, 'remark': 'Smart guy!'}
