Dictionaries in Python allow you to store key−value pairs, making it easy to organize and access data efficiently. Sometimes, we may need to retrieve specific items from nested levels within a dictionary. We can use the isinstance() with the recursion method and dict.get() method to get the nested−level items from the dictionary. In this article, we will explore different ways to get particular nested−level items from Dictionary in Python. Nested Dictionary A nested dictionary is a dictionary that contains other dictionaries as values. This allows for the creation of hierarchical structures, where data is organized in a tree−like fashion. Each ... Read More

The Hyperlink−Induced Topic Search (HITS) algorithm is a popular algorithm used for web link analysis, particularly in search engine ranking and information retrieval. HITS identifies authoritative web pages by analyzing the links between them. In this article, we will explore how to implement the HITS algorithm using the Networxx module in Python. We will provide a step−by−step guide on how to install the Networxx module and explain its usage with practical examples. Understanding HITS Algorithm The HITS algorithm is based on the idea that authoritative web pages are often linked to by other authoritative pages. It works by assigning ... Read More
