How is memory allocated for linked list elements in Python?

In Python, a linked list is usually implemented using objects where each element (node) contains data and a reference to the next element. Memory for each node is allocated dynamically on the heap, and each node is a separate object.

This means that elements are not stored in a contiguous block of memory like in an array, but are distributed across different addresses. References (pointers) within nodes allow traversal from one element to another.

Example of a linked list node:

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

# Creating nodes
node1 = Node(1)
node2 = Node(2)
node1.next = node2  # Linking nodes

Thus, memory allocation occurs automatically by the Python interpreter when objects are created, and each element is stored separately with a pointer to the next.
