Comment on Iterators, Iterables, and Generators! Oh, my! by Sumudu Fernando

Sumudu Fernando — Fri, 27 Jan 2012 09:43:42 +0000

@spititan: Your example works, but the language does require iterators to implement __iter__. What you have defined is almost an iterator, but technically isn’t one. The reason this requirement exists is that it makes it easy to write functions that can accept either an iterable or an iterator, the same way that built-ins such as sum can.

More precisely, if we write a loop like:

for x in iter(foo):
pass

then foo can be either an iterable or an iterator.

One thing about the examples in the article is that they are slightly more complicated than necessary. For example, I would write:

def forward(self):
for c in self.data:
yield ord(c)

and

def reverse(self):
for c in reversed(self.data):
yield ord(c)

(though maybe the reversed built-in did not exist when the article was written)
