A list of lists is a common data structure in Python, used for handling multi-dimensional data, matrix operations and hierarchical data processing. Python provides several ways to manipulate and transform lists of lists, including sorting, merging, filtering and converting them into different formats.
This collection of Python programs focuses on various techniques for working with lists of lists, such as flattening, sorting, counting elements, merging duplicates, and performing mathematical operations on nested lists. Whether you're dealing with structured data, matrix computations, or hierarchical lists, these programs will help you apply different list-handling techniques efficiently.
