Access and modify list when inheriting from list class python

Question

I'm inheriting from the python list class but I can't seem to figure out how to modify the list itself like below:

class MyList(list):
    def __init__(self):
        super().__init__()
        
        self = [0, 0, 0, 0]

a = MyList()
print(a) # [] instead of [0, 0, 0, 0]

@AbdulNiyasPM No, I would like to change the list itslef not only how it shows when you print — lordcommander

Subclassing list is a little bit tricky. Maybe you could subclass collections.UserList instead? — Matthias

You need to pass the list in your parent's class initializer super().__init__([0, 0, 0, 0]). and you should notice that subclassing built-in collections may result in odd behaviors. Check this link for more information.
