https://docs.python.org/2.6/library/collections.html#collections.deque has this line "Changed in version 2.6: Added maxlen parameter." https://docs.python.org/2.7/library/collections.html#collections.deque kept the sentence above and added this entry after the list of methods. Deque objects also provide one read-only attribute: maxlen Maximum size of a deque or None if unbounded. New in version 2.7. Which is it?

'parameter' and 'attribute' are two different things. I presume the documentation is accurate, but haven't checked :)

I checked and 2.6 python has maxlen as a parameter, but not a maxlen attribute. The maxlen attribute was added in 2.7.

Thanks for checking. Closing.
