5. "22323.11" 6. '*&%$#'
A list is a sequence of multiple values in a sequence. In a list, each element or value is called an
item. A list is mutable, which means the items in a list can be modified by assigning new values.
It is heterogeneous in nature, which means a list can contain numeric as well as character data.
In this chapter, you will learn about creating a list, operations performed on the list, and the functions
of the list.
CREATING A LIST
Python uses lists to store the sequential order of different kinds of data. Because Python lists are
changeable types, we can change their elements after they’ve been generated. Although Python has six
data types that may hold sequences, the list is the most popular and dependable form.
To create a list, you need to place all the elements separated by a comma inside a square bracket [ ]. The
list can contain any number of elements of different data types such as integer, float, character and so
on.
Syntax to Create a List:
<list_name> = [value1, value 2, value 3, ...]
An empty list is a list that does not contain the items in it. The example of the empty list is given as
follows:
To create empty list:
List1 = []
Some other examples of the list are given as follows:
To create list of 4 integer elements: L1 = [1, 2, 3, 4]
To create list of characters: L1 = [’a’, ’b’, ’c’]
To create list of 3 strings: L1 = [“Nikhil”, “Dikshant”, “Jatin”]
To create list of integer and float numbers: L1 = [1, 1.5, 2.5, 7]
To create list with mixed data types: L1 = [7, “Hello”, 3.14]
