How to Delete an Element from a List in Python

In Python, there are several methods available that allow the user to remove elements from a list.

remove()

The remove() method will remove the first instance of a value in a list.

list = [1, 2, 3, 1]
#remove the first instance of the value
list.remove(1)

Output:

[2, 3, 1]

pop()

The pop() method removes an element at a given index, and will return the removed item.

numbers = [10, 20, 30, 40]
ten = numbers.pop(0)
print(numbers)
print(ten) 

Output:

[20, 30, 40]
10

del

The del keyword in Python is also used to remove an element or slice from a list.

numbers = [1,2,3,4,5,6,7,8,9]
del numbers[3:6]
print(numbers)

Output:

[1, 2, 3, 7, 8, 9]
