Python List pop function is one of the List functions, which removes an item from the existing list at a user-specified index. In this section, we discuss how to use this Python pop function with a practical example. The syntax of the Python list pop function is
list_name.pop(index_value)
Remember, the Index position starts at 0 and ends at n-1.
Python List pop example
The below code removes items at index position 1 and 2. You can display the removed item by assigning the value to a new variable. For example, b = a.pop(1) returns 20.
TIP: Please refer to List article to understand everything about Python Lists and List functions.
# Python Pop List Items
a = [10, 20, 30, 40]
print("Original List Items are : ", a)
a.pop(1)
print("List Items are : ", a)
a.pop(2)
print("List Items are : ", a)
List pop function output
Original List Items are : [10, 20, 30, 40]
List Items are : [10, 30, 40]
List Items are : [10, 30]Python List pop first, second
In this example, we declared a string list. Next, we used pop function to remove items at index position 1 and 2.
# Python Pop List Items
Fruits = ['Apple', 'Orange', 'Banana', 'Kiwi', 'Grape']
print("Original List : ", Fruits)
Fruits.pop(1)
print("List Items are : ", Fruits)
Fruits.pop(2)
print("List Items are : ", Fruits)
Python pop Example 3
Let me use this pop function on Mixed List. Here, we declared a mixed list of numbers and words. Next, we used the list pop function to remove items at index 1 and 2.
# Python Pop List Items
MixList = ['apple', 1, 'Orange', 5, 'Kiwi', 'Mango']
print("Original List : ", MixList)
MixList.pop(1)
print("List Items are : ", MixList)
MixList.pop(2)
print("List Items are : ", MixList)
Mixed List pop function output
Original List : ['apple', 1, 'Orange', 5, 'Kiwi', 'Mango']
List Items are : ['apple', 'Orange', 5, 'Kiwi', 'Mango']
List Items are : ['apple', 'Orange', 'Kiwi', 'Mango']Python Program to Remove List Items
This program removes or pops nested list items at the index position 2 and 3.
# Python Pop List Items
Nested = [[71, 222], [22, 13], [11, 22], [44, 55], [99, 77]]
print("Original List : ", Nested)
Nested.pop(2)
print("List Items are : ", Nested)
Nested.pop(3)
print("List Items are : ", Nested)
Nested List pop function output
Original List : [[71, 222], [22, 13], [11, 22], [44, 55], [99, 77]]
List Items are : [[71, 222], [22, 13], [44, 55], [99, 77]]
List Items are : [[71, 222], [22, 13], [44, 55]]
