calling __init__ more than once?

[Al Gonzalez]

There doesn't seem to be a reason why you can't.

I prefer to move things into a method that can be called
from multiple places including __init__.  This keeps me
from accidentally doing things again that I only want to
happen when the class is created - such as gathering
resources..

class myParser:
    def __init__(self):
        self._prepareEnvironment()
    def parse(self, fileName):
        self._prepareEnvironment()
        # do stuff with fileName
    def _prepareEnvironment(self):
        # utility method to clear up variables
        self._fileName = None
        self._buffer = []
