The remaining functionality is the same as for the dict class and is not documented here. The first argument provides the initial value for the default_factory attribute; it defaults to None. All remaining arguments are treated the same as if they were passed to the dict constructor, including...
Passing an integer value representing the desired sample width through the enumeration’s constructor returns the right encoding instance. Once you determine the encoding of a particular WAV file, you’ll want to use your PCMEncoding instance to decode the binary audio frames. Before you do, howev...

If you don't provide an initial state in the state machine constructor, transitions will create and add a default state called 'initial'. If you do not want a default initial state, you can pass initial=None. However, in this case you need to pass an initial state every time you add ...
