[Tutor] Subclassing a module's class.

[Conrad]

I'm trying to subclass a class (HelpFormatter) from a module (optparse),
so that all calls will use my Helpformatter instead of
optparse.HelpFormatter.Currently I'm trying it like this:

import optparse

class HelpFormatter(optparse.HelpFormatter):
        def format_option(self, option):
		print "Hello, World!"

parser = optparse.OptionParser()
print parser.print_help

print_help() in optparse calls the class HelpFormatter. Can anyone
explain to me why it doesnt use my HelpFormatter?

Thanks for the time,
	Conrad
