Declaring lists

Learn to declare lists with [].

A list is an ordered, mutable collection. It is written with square brackets []:

fruits = ["Apple", "Pear", "Banana"]
numbers = [10, 20, 30]
mixed = [1, "two", 3.0]

Lists can hold items of different types. Since they are ordered, the order of items is preserved. An empty list is written as [].

The biggest advantage of lists is mutability: you can change them later with append, insert, remove.

Empty and single-item lists

An empty list is written as []. A single-item list uses the same structure:

empty = []
single = [42]

An empty list can be filled later with append. This is a common way to collect data from the user.

Assign fruits = ["Apple", "Pear", "Banana"]. Print print(fruits).
