class letter

so i just have a silly question but for the code challenge we are suppose make a loop through pattern and our code belongs in the parent class, how does python know what we are looping through if what we need to loop through is in the sub class. i know that a parent class can't inherit what's in the child class. right? this is a silly question and i hope it makes sense.

i just need a little clarification

class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern

class S(Letter):
    def __init__(self):
        pattern = ['.', '.', '.']

Good question. The challenge asks you to create a __str__ method in Letter. If this method is not overwritten the child class, it is available to run in the child class as if it were local to the child class. So a method that loops over self.pattern in the parent class will also work in the child class. Both will operate on the instance attribute pattern.

Post back if you need more help. Good luck!!!
