I know in c++ it already exist
#include <list>
Now I am curious to know if it exist in python also.
You can also take a look at llist
python package, which provides some useful features that deque
does not. There are not only doubly linked lists, but also single linked lists data structure in that package. IMHO, one of the biggest advantages of this package is the ability to store a reference to the llist elements.
