Access Class Properties through Instance Name
Can I access class properties through an instance name?
✍: FYIcenter.com
Yes, you can access class properties through an instance name, as long as there is no instance property that has the same name as a class property.
When you reference a property through the instance name in the following form:
instance_name.property_name
Python will search for the given property name in instance_name.__dict__ first. If match found, return the value. If not match found, continue with the next step.
In the next step, Python will search the given property name in class_name.__dict__. If match found, return the value. If not match found, return error.
The following Python code shows you a good example of accessing class property through a instance name:
>>> 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.nextID 2
