collections.deque "TypeError: iter() returned non-iterator of type 'deque_iterator'"

[Asher Wolfstein]

When I run the following code with Brython:

import collections

d = collections.deque([1, 6, 2, 4])

if I try to run "d = list(d)" or any kind of list comprehension I get the following error:

"TypeError: iter() returned non-iterator of type 'deque_iterator'"

Any help?

Thanks for reporting this. Bug are usually reported on the Github issue tracker, but i's ok to report them here too.

The issue was due to module _collections.py, copied from PyPy for Python version 2.x, where iterators implement method next() instead of __next__().

It's fixed in the latest commit.

I'm a little new to open source collaboration, so next time I'll try to go through the github issue tracker.  Thanks!
