I know in c++ it already exist #include <list> Now I am curious to know if it exist in python also.

Linked List in Python: To start with Python, it does not have a linked list library built into it like the classical programming languages. Python does have an inbuilt type list that works as a dynamic array but its operation shouldn't be confused with a typical function of a linked list.
Python doesn't ship with a built-in linked list data type in the “classical” sense. Python's list type is implemented as a dynamic array—which means it doesn't suit the typical scenarios where you'd want to use a “proper” linked list data structure for performance reasons.
Unlike other general purpose languages, Python does not have a built-in implementation of Linked Lists in its standard library. In today's article we will explore how to implement a user-defined Linked List class using Python.
A node is implemented as a class named ListNode . The class contains the definition to create an object instance, in this case, with two variables - data to keep the node value, and next to store the reference to the next node in the list.
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.
