Its syntax is also similar to a dictionary: movie_titles = { "2001: a space odyssey", "Blade Runner", "Blade Runner 2049" } However, sets are not for storing information associated with a given key.

The dictionary functions in a similar fashion to the Python list, in that it is a collection of data. In this case, however, dictionaries hold key-value pairs instead of single values.

While Python has lacked a native syntax for pattern matching, it has been possible to emulate it with if/elif/else chains or a dictionary lookup.
