Example: class PatternGenerator(object): """Run a regex.....""" def __init__(self, type_): self.type = type_ def __call__(self, pattern, parameter): return pattern_generator(self, self.type, pattern, parameter) # Initialize class setpattern_iis = PatternGenerator('iis') # call the method here setpattern_iis("pattern", "params") Hope that helps, Vince
