The RFC commands constitute the protocol between FTP servers/clients and are
specified (reasonably) exactly to get good interworking between different
implementations.  The dir, ls, get etc commands constitute the user interface
and are modelled on what a user on that system might expect to know.  The
Python library, unusually for Python, does not do much in the way of hiding
the protocol level commands.  Perhaps there are some 3rd party addons to add a
more user friendly level, the vaults of Parnassus
(http://www.vex.net/parnassus/) seems to have some promising libraries.
