try to inherit or change "name" attribute in "my_function".

Thanks Chris! 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.
