Since the previous reply answers your first question, I'll talk aboutprogramming
style.  I would tend to write a ReInit function since
__init__ really means "called when you create the object".  However,
there is nothing illegal about calling __init__ directly.

class huh:
    def __init__(self):
        # some one-time initialization code
        print "spammity"
        self.ReInit()

    def ReInit(self):
        # some code
        print "spam"

>>> h = huh()
spammity
spam
>>> h.ReInit()
spam

The only time __init__ is usually called is from a derived object:

class what(huh):
    def __init__(self):
        huh.__init__(self)
        # more initialization for what

Legal, but don't do that.  People will think you are a C programmer :-) Ack!
