List Methods in Python | Set 2 (del, remove(), sort(), insert(), pop(), extend()…)

Last Updated : 07 Apr, 2025

Some of the list methods are mentioned in set 1 below

More methods are discussed in this article.

1. del[a : b]

:- This method

deletes all the elements in range

starting from index ‘a’ till ‘b’ mentioned in arguments.

2. pop()

:- This method

deletes

the element

at the position

mentioned in its arguments.

Python

# Python code to demonstrate the working of
# del and pop()

# initializing list 
lis = [2, 1, 3, 5, 4, 3, 8]

# using del to delete elements from pos. 2 to 5
# deletes 3,5,4
del lis[2 : 5]

# displaying list after deleting 
print ("List elements after deleting are : ",end="")
for i in range(0, len(lis)):
    print(lis[i], end=" ")
    
print("\r")

# using pop() to delete element at pos 2
# deletes 3
lis.pop(2)

# displaying list after popping  
print ("List elements after popping are : ", end="")
for i in range(0, len(lis)):
    print(lis[i], end=" ")

Output:

List elements after deleting are : 2 1 3 8 
List elements after popping are : 2 1 8

3. insert(a, x)

:- This function

inserts an element at the position

mentioned in its arguments. It takes 2 arguments,

position and element to be added at respective position.

4. remove()

:- This function is used to

delete the first occurrence

of number mentioned in its arguments.

Python

# Python code to demonstrate the working of
# insert() and remove()

# initializing list 
lis = [2, 1, 3, 5, 3, 8]

# using insert() to insert 4 at 3rd pos
lis.insert(3, 4)

# displaying list after inserting
print("List elements after inserting 4 are : ", end="")
for i in range(0, len(lis)):
    print(lis[i], end=" ")
    
print("\r")

# using remove() to remove first occurrence of 3
# removes 3 at pos 2
lis.remove(3)

# displaying list after removing 
print ("List elements after removing are : ", end="")
for i in range(0, len(lis)):
    print(lis[i], end=" ")

Output:

List elements after inserting 4 are : 2 1 3 4 5 3 8 
List elements after removing are : 2 1 4 5 3 8

5. sort()

:- This function

sorts

the list in

increasing order

6. reverse()

:- This function

reverses

the elements of list.

Python

# Python code to demonstrate the working of
# sort() and reverse()

# initializing list 
lis = [2, 1, 3, 5, 3, 8]

# using sort() to sort the list
lis.sort()

# displaying list after sorting
print ("List elements after sorting are : ", end="")
for i in range(0, len(lis)):
    print(lis[i], end=" ")
    
print("\r")

# using reverse() to reverse the list
lis.reverse()

# displaying list after reversing
print ("List elements after reversing are : ", end="")
for i in range(0, len(lis)):
    print(lis[i], end=" ")

Output:

List elements after sorting are : 1 2 3 3 5 8 
List elements after reversing are : 8 5 3 3 2 1

7. extend(b)

:- This function is used to

extend the list with

the elements present in

another list

. This function takes

another list as its argument

8. clear()

:- This function is used to

erase all the elements

of list. After this operation, list becomes empty.

Python

# Python code to demonstrate the working of
# extend() and clear()

# initializing list 1
lis1 = [2, 1, 3, 5]

# initializing list 1
lis2 = [6, 4, 3]

# using extend() to add elements of lis2 in lis1
lis1.extend(lis2)

# displaying list after sorting
print ("List elements after extending are : ", end="")
for i in range(0, len(lis1)):
    print(lis1[i], end=" ")
    
print ("\r")

# using clear() to delete all lis1 contents
lis1.clear()

# displaying list after clearing
print ("List elements after clearing are : ", end="")
for i in range(0, len(lis1)):
    print(lis1[i], end=" ")

Output:

List elements after extending are : 2 1 3 5 6 4 3 
List elements after clearing are :
