# How to Store Ordered Data List
In Python, a `List` is a datatype that represents **ordered data**. It allows storing and modifying elements of various data types.
Lists are created by enclosing elements in square brackets `[]` and separating each element with a comma (`,`).
Each element in a list can be accessed by an `Index`.
An index is a number that indicates the **position of a specific element** within a data structure containing sequential elements, such as a list.
Indices in a list start at `0`, with `0` referring to the first element in the list.
```python title="Example of a List"
# Creating a list of integers
numbers = [100, -2, 32, 450]
In the example above, the elements at each index in the numbers list are as follows:
-
numbers[0]: 100 -
numbers[1]: -2 -
numbers[2]: 32 -
numbers[3]: 450
What Data Can Be Stored in a List?
Lists can store various types of data, such as integers, strings, and other lists.
Characteristics of a List
# Creating a list that includes various data types
mixed = [1, "apple", True, 3.14]
In the example above, the mixed list includes elements of various data types such as an integer, string, boolean, and floating-point number.
Moreover, lists can contain other lists as well.
List Containing Various Data Types
mixed_list = [1, "apple", ["Python"]]
In the example above, the third element of mixed_list, i.e., mixed_list[2], includes another list ["Python"].
