Overriding constructors for list in python

Question

Let's say I want to implement some list class in python with extra structure, like a new constructor. I wrote:

import random

class Lis(list):
    def __init__(self, n):
        self = []
        for i in range(n):
            self.append(random.randint(0, 30))

Now doing Lis(3) gives me an empty list. I don't know where I did it wrong.

Answer 1

You are overriding the object with self = []

try the following

import random

class Lis(list):
    def __init__(self, n):
        for i in range(n):
            self.append(random.randint(0, 30))
