Example 4: python how to remove elements from a list

# Basic syntax:
my_list.remove(element)

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

# Example usage:
animals = ['cat', 'dog', 'rabbit', 'guinea pig', 'rabbit']
animals.remove('rabbit')
print(animals)
--> ['cat', 'dog', 'guinea pig', 'rabbit'] # Note only 1st instance of
#	rabbit was removed from the list. 

# Note, if you want to remove all instances of an element, convert the
#	list to a set and back to a list, and then run .remove(element)	E.g.:
animals = list(set['cat', 'dog', 'rabbit', 'guinea pig', 'rabbit']))
animals.remove('rabbit')
print(animals)
--> ['cat', 'dog', 'guinea pig']
