Hi Syed and all,

I tried implementing linked list based on the learnings from the class
Here is the code I wrote,

github.com

parameshwar-A/dsa-notes/blob/main/linked_list.py

class Node:
    def __init__(self, value):
        self.value = value
        self.next = None

    def __str__(self):
        return f"({self.value}, {self.next})"

class LinkedList:
    def __init__(self, head=None):
        self.head = head

    def append(self, new_item):
        current=self.head
        if current:
            while current.next:
                current=current.next
            current.next=new_item
        else:
            self.head=new_item

Let me know you can find any issues / errors from this code

See you guys in today’s evening sesssion
