Hashmaps and dictionaries are two of the most commonly used data structures in Python. They allow us to store key-value pairs, meaning each value is associated with a unique key.

This makes it easy to look up a value based on its key. In this tutorial, we will discuss the differences between hashmaps and dictionaries and the advantages and disadvantages of each.

Are you looking for an efficient way to find the middle node of a singly linked list in Python? In this post, we’ll go through the different steps of finding the middle node of a singly linked list in Python, such as understanding the concept of singly linked lists, how to traverse one, and how to find the middle node. Keep reading/watching to learn more!
