Hi, List the test code as attached
first i tried map, and failed, then i turned to partial from functools the latter one works, i wonder if there is unseen tricky from me between them :) this one works >>>>print p.map(partial(file_op,lineop=unity),input) this one doesn't work >>>>print p.map(lambda x:file_op(x,unity), input) Thanks. -- Liu An Institution of modern physics, Shanghai, China _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
