Why Kenneth in the beginning of class initiates attribute?
The question as in the title. This is my files of attributes, thieves, character:
import random class Sneaky: def __init__(self, sneaky=True, *args, **kwargs): super().__init__(*args, **kwargs) self.sneaky = sneaky def hide(self, light_level): return self.sneaky and light_level < 10
class Agile: def __init__(self, agile=True, *args, **kwargs): super().__init__(*args, **kwargs) self.agile = agile def evade(self): return self.agile and random.randint(0, 1)
import random from characters import Character from attributes import Agile, Sneaky class Thief(Sneaky, Agile, Character): def pickpocket(self): return self.sneaky and bool(random.randint(0, 1))
class Character: def __init__(self, name='', **kwargs): self.name = name for key, value in kwargs.items(): setattr(self, key, value)
Sorry for format, but I can't see options for formatting. Anyway, I didn't it what Kenneth did and it works all fine. I mean he writes agile = True in the beginning Agile class, I don't know why.

Good Question. You are correct that, since the class instances set the attributes during instance initialization, they do not also need attributes to be set in the class.
One situation that would warrant setting in both the class and in
__init__ is if a classmethod relied on the attribute. When running classmethods there is no instance and hence no
I'm taking the oop course again to understand more. Can you please explain how can we use super() in parent class in attributes.py. I thought super() is used only in the subclass to call parent class init method. I tried to run the code in Jupyter notebook, I get en error which says that 'init' takes one exactly argument which makes sense.
