If it doesn't get too complex you could start with Python's built-in string formatting: import sys template = '''\ #!/usr/bin/python from PythonCard import model class {Class}(model.Background): pass if __name__ == '__main__': app = model.Application({Class}) app.MainLoop() ''' resourcename, filename = sys.argv[1:] with open(resourcename, "U") as f: data = eval(f.read()) with open(filename, "w") as f: f.write(template.format(Class=data["application"]["name"])) If you need logic inside the template, here's on overview: http://wiki.python.org/moin/Templating So there are rather too many options than too few. -- http://mail.python.org/mailman/listinfo/python-list
