10.2. List ValuesΒΆ
There are several ways to create a new list. The simplest is to
enclose the elements in square brackets ( [
and ]
).
[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 have to be the
same type. There is also 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. Like other variables, when
creating a list variable the type must be specified when it is
declared. Unlike other variables, the list type changes depending on
the type of the elements in the list. List types use square brackets
( [
and ]
) to surrond the type of the elements in the list.
