Even though "__getitem__" method is enough for now, you should implement "__iter__" method as well for later compatibility. A classic iterator Below is a classic implementation - not a rolemodel - of an iterator. import re import reprlib class Sentence: def __init__(self, text): self.tex..

1. Iterator __iter__, __next__를 가진 객체를 iterator protocol을 지원한다고 일컫는다. class Counter: def __init__(self, limit): self.num = 0 self.limit = limit def __iter__(self): return self def __next__(self): if self.num < self.limit: ret = self.num self.num += 1 return ret else: raise StopIteration for i in Counter(10): print(i, end=' ') 클래스에서 __getitem__ 메서드만 구현해도 이터레이터가 된다. class Counter: def __init__(sel..
