I've changed some code that used a list to using a deque. I can no longer slice into it, as I get the error:

TypeError: sequence index must be integer, not 'slice'

Here's a REPL that shows the problem.

>>> import collections
>>> d = collections.deque()
>>> for i in range(3):
...     d.append(i)
...
>>> d
deque([0, 1, 2])
>>> d[2:]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: sequence index must be integer, not 'slice'

So, is there a workaround to support slicing into deques in Python?

python slice deque
