I'll check that link. Test.py #!/usr/bin/python from my_lib import p_test class my_class(p_test.name): def __initial__(self, name): pass def test(self): print "this is a test" If __name__ == '__main__': my_class.main() --------------------------------------------------- my_lib.py class p_test() ....... ........ Can anyone finish it and give me a demo. Class inheritance? for this case, it inherit/change p_test "name" attribute. I try to quick understand how to inherit parent attribute TIA. david -- http://mail.python.org/mailman/listinfo/python-list
