returning results from plsql function to plpythonu function

Hello friends,
I am checking some logic which includes two functions. One is plsql
function which returns text. Second function is plpythonu and contains one
statement which outputs notice

e.g.
results = plpy.execute("select * from software.func1();")
plpy.notice("%s" % col for col in results[0])

The same result is returned as a final return as notice. But it does not
outputs the correct result which is returned from func1 (text in this
case). Rather it outputs notice as
NOTICE: <generator object <genexpr> at 0xb578cb6c>
It doesn't prints the correct notice even by using
plpy.notice("%s" %results)

What can be the problem here?
Thanks for help.
