Help, subclass in Python, I don't see the parent class in the video

class FilledList(list): class JavaScriptObject(dict):

There are two class code in the video but I don't see where are the class list and class dict, where do they come from and how do they use as a parent class?

Hi Hanwen!

Lists and dictionaries (dict) are native Python data type/structures.

More info:

I hope that helps.

Stay safe and happy coding!
