You can directly iterate over the keys of a Python dictionary using a for loop and access values with dict_object[key]. You can iterate through a Python dictionary in different ways using the dictionary methods .keys(), .values(), and .items(). You should use .items() to access key-...
That creates a new dictionary object. If wereallywanted to update our original dictionary object, we could take the items from the dictionary, sort them, clear the dictionary of all its items, and then add all the items back into the dictionary: >>>old_dictionary={"Pink":"Rm 403","Spac...
