What is the difference between Del and remove() on lists in Python?

Before discussing the differences, let’s understand what Del and Remove() are in Python lists.

Del keyword in Python list

The del keyword in Python is used to delete one or more elements from a List. We can also delete all elements, i.e. delete the entire list.

Example

Use the del keyword to delete elements from a Python list

#Create a List myList = ["Toyota", "Benz", "Audi", "Bentley"] print("List = ",myList) # Delete a single element del myList[2] print("Updated List = \n",myList)

Copy after login

Output

List = ['Toyota', 'Benz', 'Audi', 'Bentley'] Updated List = ['Toyota', 'Benz', 'Bentley']

Copy after login

Example

Use the del keyword to delete multiple elements from a Python list

# Create a List myList = ["Toyota", "Benz", "Audi", "Bentley", "Hyundai", "Honda", "Tata"] print("List = ",myList) # Delete multiple element del myList[2:5] print("Updated List = \n",myList)

Copy after login

Output

List = ['Toyota', 'Benz', 'Audi', 'Bentley', 'Hyundai', 'Honda', 'Tata'] Updated List = ['Toyota', 'Benz', 'Honda', 'Tata']

Copy after login

Example

Use the del keyword to remove all elements from a Python list

# Create a List myList = ["Toyota", "Benz", "Audi", "Bentley"] print("List = ",myList) # Deletes the entire List del myList # The above deleted the List completely and all its elements

Copy after login

Output

List = ['Toyota', 'Benz', 'Audi', 'Bentley']

Copy after login

Remove() method in Python list

The remove() built-in method in Python is used to remove elements from List.

Example

Use the remove() method to remove elements from Python

# Create a List myList = ["Toyota", "Benz", "Audi", "Bentley"] print("List = ",myList) # Remove a single element myList.remove("Benz") # Display the updated List print("Updated List = \n",myList)

Copy after login

Output

List = ['Toyota', 'Benz', 'Audi', 'Bentley'] Updated List = ['Toyota', 'Audi', 'Bentley']

Copy after login

Delete and delete()

Now let us see the difference between del and remove() in Python -
