__setitem__ implementation in Python for Point(x,y) class

Question

I\'m trying to make a Point class in python. I already have some of the functions, like __ str__ , or __ getitem__ implemented, and it works great. The only problem I\'m fac

Answer 1

Here's an example:

from collections import namedtuple

Deck = namedtuple('cards',['suits','values'])

class FrenchDeck(object):

    deck = [str(i) for i in range(2,11)]+list('JQKA')
    suits = "heart clubs spades diamond".split()

    def __init__(self):
        self.totaldecks = [Deck(each,every) for each in self.suits for every in self.deck]
    def __len__(self):
        return len(self.totaldecks)
    def __getitem__(self,index):
        return self.totaldecks[index]
    def __setitem__(self,key,value):
        self.totaldecks[key] = value

CardDeck = FrenchDeck()
CardDeck[0] = "asdd"       # needs`__setitem__()`
print CardDeck[0]

If you don't use the __setitem__(), you will get an error

TypeError: 'FrenchDeck' object does not support item assignment
