Normally this is done when you instantiate the class:

fp = open('dummyFile.txt')
curHandler=LogHander(fp)

class LogHandler(ContentHandler):
    def __init__(self, fp=None):
        self.fp=fp

    def endElement(self, name:
        doSomething(self, "GroupResultList", self.text, self.fp)


but you could set it later if you like:

fp = open('dummyFile.txt')
curHandler=LogHander()
curHandler.fp=fp
