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 that contains sequential elements, like a list.

Indexes in a list start from 0, with 0 pointing to the first element in the list.

Copy
# Creating a list of integers
numbers = [100, -2, 32, 450]

In the example above, the elements corresponding to each index in the numbers list are as follows:

• numbers[0]: 100

• numbers[1]: -2

• numbers[2]: 32

• numbers[3]: 450

Lists can store various types of data, such as integers, strings, and other lists.

Copy
# 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.

Copy
mixed_list = [1, "apple", ["Python"]]

In the example above, the third element of mixed_list, i.e., mixed_list[2], includes another list ["Python"].
