Python - Remove List Items

---

The list class methods remove() and pop() both can remove an item from a list. The difference between them is that remove() removes the object given as argument, while pop() removes an item at the given index.

Using the remove() Method

The following example shows how you can use the remove() method to remove list items −

list1 = ["Rohan", "Physics", 21, 69.75]
print ("Original list: ", list1)

list1.remove("Physics")
print ("List after removing: ", list1)

It will produce the following output −

Original list: ['Rohan', 'Physics', 21, 69.75]
List after removing: ['Rohan', 21, 69.75]

Using the pop() Method

The following example shows how you can use the pop() method to remove list items −

list2 = [25.50, True, -55, 1+2j]
print ("Original list: ", list2)
list2.pop(2)
print ("List after popping: ", list2)

It will produce the following output −

Original list: [25.5, True, -55, (1+2j)]
List after popping: [25.5, True, (1+2j)]

Using the "del" Keyword

Python has the "del" keyword that deletes any Python object from the memory.

Example

We can use "del" to delete an item from a list. Take a look at the following example −

list1 = ["a", "b", "c", "d"]
print ("Original list: ", list1)
del list1[2]
print ("List after deleting: ", list1)

It will produce the following output −

Original list: ['a', 'b', 'c', 'd']
List after deleting: ['a', 'b', 'd']

Example

You can delete a series of consecutive items from a list with the slicing operator. Take a look at the following example −

list2 = [25.50, True, -55, 1+2j]
print ("List before deleting: ", list2)
del list2[0:2]
print ("List after deleting: ", list2)

It will produce the following output −

List before deleting: [25.5, True, -55, (1+2j)]
List after deleting: [-55, (1+2j)]
