Section 10.2 List Values
There are several ways to create a new list. The simplest is to enclose the elements in square brackets (
[10, 20, 30, 40] ["spam", "bungee", "swallow"]
The first example is a list of four integers. The second is a list of three strings. As we said above, the elements of a list don't have to be the same type. The following list contains a string, a float, an integer, and another list.
["hello", 2.0, 5, [10, 20]]
A list within another list is said to be nested and the inner list is often called a sublist. Finally, there is a special list that contains no elements. It is called the empty list and is denoted
As you would expect, we can also assign list values to variables and pass lists as parameters to functions.
Check your understanding
- Yes, unlike strings, lists can consist of any type of Python data.
- Lists are heterogeneous, meaning they can have different types of data.
A list can contain only integer items.
