I have since updated each ship's
__init__ to accept all the arguments that Craft accepts so that I can
support all optional arguments,
Ick. Now you'll have to change several things if you make one change to
the Craft class. Better to do it this way:
[borrowing Peter's example]
class Craft(object):
def __init__(self, name, id=None, weapons=None):
if id is None:
id = helpers.id()
if weapons is None:
weapons = []
self.name = name
self.id = id
self.weapons = weapons
class Battleship(Craft):
def __init__(self, name, max_hits=None, **kwds):
Craft.__init__(self, name, **kwds)
self.max_hits = max_hits
Notice the **kwds in Battleships's init, both in the parameter line, and
in the call to Craft's init. This way all keyword arguments that
Battleship doesn't directly support will be passed through to Craft.
