(Recommended tutorial:python tutorial)

remove() function Used to remove the first occurrence of a value in a list.

remove() method syntax:

list.remove(obj)

If obj is not in the list, a ValueError error will be raised. Usually, the count method is used to check how many obj there are.

pop() method syntax:

list.pop(obj=list[-1])

Example:

1. pop() function

>>> a = [3, 2, 1] >>> a.pop(1) 2 >>> a [3, 1]
