Linked List using PYTHON

This is a gentle intro into data structures using python.This is my personal learning experience and to take a note of what i am learning.Please feel free to comment

In this post I have tried to implement a simple Linked List using Python.

First I have created a file named LList.py which will contain the following code.Then i would be using this as a module in my main file to create a implementation using these

#Single node creation class

class Element:

    def __init__(self, x):

        self.data = x

        self.next = None

#Linked List implementation class

class LinkedList:

    def __init__(self):

        self.head = None

        self.tail = None

    def append(self, x):

        e = Element(x)

        if self.head is None:

            self.head = e

            self.tail = e

        else:

            self.tail.next = e

            self.tail = e

    def showlist(self):

        e = self.head

        while e.next is not None:

            print e.data

            e = e.next

        print e.data

Now lets make a new file called ListMain.py and have the following code:

import LList

#Adding 5 elements to list and showing it

if __name__ == '__main__':

    testList = LList.LinkedList()

    testList.append(1)

    testList.append(2)

    testList.append(3)

    testList.append(4)

    testList.append(5)

    testList.showlist()

Try running in command line the : python ListMain.py 

Hope it was useful :)
