List Within a List in Python – How to Initialize a Nested List
In Python, you can also have lists within a list. And that's what we'll discuss in the next section. A list within another list is referred to as a nested list in Python. We can also say that a list that has other lists as its elements is a nested list. When we want to keep several sets of connected data in a single list, this can be helpful.

Python Nested List - Learn By Example
Nested lists in Python are lists that contain other lists as their elements. This structure allows you to create multi-dimensional data representations, which are particularly useful when working with matrices, tables, or other complex data arrangements.

Python Lists - GeeksforGeeks
In Python, a list is a built-in dynamic sized array (automatically grows and shrinks). We can store all types of items (including another list) in a list. A list may contain mixed type of items, this is possible because a list mainly stores references at contiguous locations and actual items maybe stored at different locations.

Iterating through indexes of nested lists in Python
Can anyone tell me how can I call for indexes in a nested list? Nlist = [[2, 2, 2], [3, 3, 3], [4, 4, 4], ...] and I want to go through the indexes of each one separately? You need to rewrite your question and make it clear. Your use of “indexes” is suspect; perhaps you meant “items”?

Python List (With Examples) - Programiz
In Python, lists allow us to store multiple items in a single variable. For example, if you need to store the ages of all the students in a class, you can do this task using a list. Lists are similar to arrays (dynamic arrays that allow us to store items of different data types) in other programming languages.
