## Lists
Lists is one of the most common Python data structures you will encounter while programming in Python along with dictionary, tuple or set.
It is an ordered mutable collection, this means that you store data in different postions in a list.
A `list` is an ordered mutable collection, where each value is identified with an *index*. Lists are zero-indexed, i.e., the index of the **1st** element in a `list` is **0**, the index of the **2nd** element is **1**, and so on. This means that a list of **N** elements will have indices from **0** to **N - 1**(not N).
Besides that due to list being *mutable*, you are allowed to make changes to the value of a list without affecting the order of positions within the list.
