# A list is the most flexible data structure in Python

A list is the most flexible data structure in Python. Whereas, a 2D list which is commonly known as a list of lists, is a list object where every item is a list itself

A list is the most flexible data structure in Python. Whereas, a 2D list which is commonly known as a list of lists, is a list object where every item is a list itself - for example: `[[1,2,3], [4,5,6], [7,8,9]]`.

Flattening a list of lists entails converting a 2D list into a 1D list by un-nesting each list item stored in the list of lists - i.e., converting `[[1, 2, 3], [4, 5, 6], [7, 8, 9]]` into `[1, 2, 3, 4, 5, 6, 7, 8, 9]`.

The process of flattening can be performed using nested for loops, list comprehensions, recursion, built-in functions or by importing libraries in Python depending on the regularity and depth of the nested lists.
