Mar 3, 2017 · @MadPhysicist "It [deque] behaves like a linked list in almost every way, even if the name is different." — it is either wrong or meaningless: it is wrong because linked lists may provide different guarantees for time complexities e.g., you can remove an element (known position) from a linked list in O(1) while deque doesn't promise it (it is O(n)).

Oct 16, 2017 · I'm trying to learn Linked Lists in python I've been given Linked List class and asked to create append method. Here is the code provided. class Node: def __init__(self, item, next): ...

Jul 22, 2015 · I'm trying to figure out to convert a list to a linked list. I already have a class for the link but I'm trying to figure out how to convert a list to linked list, for example: def list_to_link(lst): """Takes a Python list and returns a Link with the same elements.

Oct 21, 2015 · I was thinking maybe I could use temporary values so I can someone append the beginning of the stack to a list and then somehow convert it back into a stack object. Edit for duplication: The goal of my program is use an existing Stack and reverse it. The linked post deals with a linked list that was already in a list format.

@Ramya My point is: we cannot help you if you are using a library we don't know about. We can write pseudocode showing you how to do it, but that's all around in the Internet and textbooks, and if this is homework (and looks 100% like it), you should show at least a piece of code where you try this first, and then we may correct it -as a general …

Mar 24, 2014 · First thing that jumps out at me is when you enqueue you need to increment the length of the list. size() should just need to return the length of the list once you've done that. And then to access the first item of the list you appear to be trying to use list syntax which your list does not support (at least in the code I can see).

Mar 9, 2014 · This assignment asks us to implement the append, insert, index and pop methods for an unordered linked-list. (What I have so far) def main(): class Node: def __init__(self, data):

A list in Python is something like an array, where you can store multiple values. List is mutable that means you can change it. The more important thing you should know, when we create a list, Python automatically creates a reference_id for that list variable. If you change it by assigning others variable the main list will be change.
