Pop() Function in a list in Python

What is Pop Function

Pop is an inbuilt function in python which removes the last element from the list for eg. mylist = [1,2,3,4,5] on executing the mylist.pop() the last element i.e 5 is removed from the list and we get [1,2,3,4] as output.

General syntax

list_name.pop(index)

Explanation :

• list_name is the name of your list
• pop is the inbuilt function used to delete the element
• index is the position of the element to be removed, it can also be left empty (by default it will delete the last element)
• pop function returns updated list after deletion.

Examples :

list = ['code', 'speedy', '.', 'com']

#Case 1
list1.pop()
print(list)

#Case 2
list1.pop()
print(list)

#Case 3
list1.pop(0)
print(list)

Output :

['code', 'speedy', '.']
['code', 'speedy']
['speedy']

Explanation :

• First, we need to declare a list on which we can operate.
• The first pop function deletes the last element i.e ‘com’
• Now ‘.’ is the last element and when we run the pop command the last element is deleted
• And finally, when we run the pop(0) the element in index 0 is deleted i.e ‘code’
