Because dictionaries are mutable, they can be changed in many ways. Items can be removed from a dictionary with the del command:

del dict_name[key_name]

will remove the key key_name and its associated value from the dictionary.

A new value can be associated with a key by assigning a value to the key, like so:

dict_name[key] = new_value



Delete the 'Sloth' and 'Bengal Tiger' items from zoo_animals using del.

Set the value associated with 'Rockhopper Penguin' to anything other than 'Arctic Exhibit'.
