currently I fetch "list" data from my storage, "deque" it to work with that data. After processing the fetched data I have to put them back into the storage. This won't be a problem as long as I am not forced (at least I think so) to use python's standard "list" object to save this data.
Storage Service: Google Appengine.
My work-around would be:
dequeObj = deque(myData)
my_list= list()
for obj in dequeObj:
my_list.append(obj)
but this seems not very optimal.
>>> list(collections.deque((1, 2, 3)))
[1, 2, 3]
