Dictionaries are data structures used to map arbitrary keys to values
A useful dictionary method is get. It does the same thing as indexing, but if the key is not found in the dictionary it returns another specified value instead ('None', by default).
Just like lists, dictionary keys can be assigned to different values.
To determine whether a key is in a dictionary, you can use in and not in, just as you can for a list.
