remove item from list python

1# Below are examples of 'remove', 'del', and 'pop'

9""" 'del' removes the item at a specific index: """
10>>> a = [9, 8, 7, 6]
11>>> del a[1]

1# Basic syntax:
2my_list.remove(element)

4# Note, .remove(element) removes the first matching element it finds in
5# 	the list.

7# Example usage:
8animals = ['cat', 'dog', 'rabbit', 'guinea pig', 'rabbit']
9animals.remove('rabbit')
10print(animals)
11--> ['cat', 'dog', 'guinea pig', 'rabbit'] # Note only 1st instance of
12#	rabbit was removed from the list. 
13
14# Note, if you want to remove all instances of an element, convert the
15#	list to a set and back to a list, and then run .remove(element)	E.g.:
16animals = list(set['cat', 'dog', 'rabbit', 'guinea pig', 'rabbit']))
17animals.remove('rabbit')
18print(animals)
19--> ['cat', 'dog', 'guinea pig']
