Deleting items from the list in Python

January 9, 2021

Deleting items

In python we can delete items using following methods

Pop- delete items based on index of elements
Remove- removes particular item
Del- deletes group of elements
Clear- clears entire list

We can use any of these according to the application. Lets see how each function works.

Pop:

Pop deletes based on index of the items. If index not given then it take last index of list in default . We can store the deleted item into another variable.

list1=[“channa”,“milk”,“bread”,“apples”,“salt”,“sugar”,“coconut”,“salt”]
y=list1.pop(0)
print(“Popped element :”,y) 
print(“List after poping an element at particular index\n“,list1)

Popped element : channa
List after poping an element at particular index
['milk', 'bread', 'apples', 'salt', 'sugar', 'coconut', 'salt']

Remove :

Remove deletes the item that is passed as argument for remove function. It removes first occurrence of that item.

list1=[“channa”,“milk”,“bread”,“apples”,“salt”,“sugar”,“coconut”,“salt”]

list1.remove(“salt”)
print(“List after removing an specific element\n“,list1) 

List after removing an specific element
['channa', 'milk', 'bread', 'apples', 'sugar', 'coconut', 'salt']

Del :

Del() function deletes group of elements of list at once by using slicing. del(x[:]) this will delete entire list

x=[1,2,3,56,3,3,22]
del(x[1:3])
print(“List after deleting group of elements\n“,x)

List after deleting group of elements
[1, 56, 3, 3, 22]

Clear :

Clear is used to delete entire list at same time

x=[1,2,3,56,3,3,22]

x.clear() 
print(“List after Deleting entire list “,x)

List after Deleting entire list []
