Python

Not understanding this particular code.

For some reason I am having difficulty with this particular piece of code. I cant seem to understand what I am doing wrong. I am I missing something?

Also anyone here who is doing Python or coding in general do you guys suffer from imposter syndrome & do you guys just stair at the computer screen and just feel lost and just feel like you will never understand how to do this or code for that matter, because for me I feel like I am screwing up and as a result I get frustrated (especially with OOP) and I just want to put down the keyboard and just do something else.

hands.py
from dice import D6


class Hand(list):
    def __init__(self, size=0, die_class=None, *args, **kwargs):
        if not die_class:
            raise ValueError("You must provide a die class")
        super().__init__()

        for _ in range(size):
            self.append(die_class())
        self.sort()

    def _by_value(self, value):
        dice = []
        for die in self:
            if die == value:
                dice.append(die)
        return dice


class CapitalismHand(Hand): 
    @property
    def __init__(self, *args, **kwargs):
        super().init(size=2, die_class=D6, *args, *kwargs)

    @property
    def twos(self):
        return self._by_value(2)

    @property
    def threes(self):
        return self._by_value(3)

    @property
    def fours(self):
        return self._by_value(4)

    @property
    def fives(self):
        return self._by_value(5)

    @property
    def sixes(self):
        return self._by_value(6)

    @property
    def _sets(self):
        return {
            1: len(self.ones),
            2: len(self.twos),
            3: len(self.threes),
            4: len(self.fours),
            5: len(self.fives),
            6: len(self.sixes)
        }

You're pretty close, but:

  • the "__init__" method is not a property
  • the super's method name is also "__init__" (not just "init")
  • when expanding kwargs, use the double "splat" ("**kwargs" instead of "*kwargs")
