OPERATIONS ON A LIST
There are several operations which can be performed on on the list. The following table describes
the various list operations.
Operator Operations Explanation
+ Joining lists To add/concatenate two list together by using ‘+’ operator.
* Repeating lists To multiplies a list by an integer ‘n’ and then creates a
new list which repeats the original list ‘n’ times by using’*’
operator.
: Slicing lists To access the list elements within a specific range.
= = Comparing list Check if the contents of the list are same or not by using
‘==’ operator.

list=[13, 25, 41, 63, 82]
list=[13, 25, 41, 63, 82]
list1=[23, 35, 51, 73, 92]
print(list+list1)
print(list*4)
print(list[0:4])
print(list==list1])
On running the above program, you will get the following output:
Output
[13, 25, 41, 63, 82, 23, 35, 51, 73, 92]
[13, 25, 41, 63, 82, 13, 25, 41, 63, 82, 13, 25, 41, 63, 82, 13, 25, 41,
63, 82]
[13, 25, 41, 63]
False
LIST METHODS
To make the use of list easier Python provides various built-in methods. In the above section we
have already discussed append( ) and extend( ) methods, let’s explore more methods.
The following table describes the various built-in methods.
Method Explanation
append( ) Add element at the end of the existing list
extend( ) Add more than one elements to the end of the existing list
insert(x, a) Insert element ‘a’ at the ‘x’ location of the list
