Answer» Answer: A list is an ordered SET of values, where each value is identified by an index. The values that make up a list are called its elements. LISTS are similar to strings, which are ordered sets of characters, except that the elements of a list can have any type. Lists and strings — and other things that behave like ordered sets — are called sequences. 9.1. List values 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. The elements of a list don’t have to be the same type.

Answer:

A list is an ordered SET of values, where each value is identified by an index. The values that make up a list are called its elements. LISTS are similar to strings, which are ordered sets of characters, except that the elements of a list can have any type. Lists and strings — and other things that behave like ordered sets — are called sequences.

9.1. List values

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. The elements of a list don’t have to be the same type. The following list CONTAINS a string, a float, an integer, and (mirabile dictu) another list:

["hello", 2.0, 5, [10, 20]]

A list within another list is said to be nested.

Finally, there is a special list that contains no elements. It is called the empty list, and is denoted [].

Like numeric 0 values and the empty string, the empty list is false in a boolean expression:

>>> if []:

... print 'This is true.'

... else:

... print 'This is false.'

...

This is false.

>>>

With all these ways to create lists, it would be disappointing if we couldn’t assign list values to variables or pass lists as parameters to functions. We can:

>>> vocabulary = ["ameliorate", "castigate", "defenestrate"]

>>> NUMBERS = [17, 123]

>>> empty = []

>>> print vocabulary, numbers, empty

['ameliorate', 'castigate', 'defenestrate'] [17, 123] []

9.2. Accessing elements

The syntax for accessing the elements of a list is the same as the syntax for accessing the characters of a string—the bracket operator ( [] – not to be confused with an empty list). The expression inside the brackets specifies the index. Remember that the indices start at 0:
