Actually even with ASCII (read for python 2.7) I would also be happy to have such function: say I just want to keep only digits so I write: digits = "0123456789" newstring = somestring.keep(digits) Despite I can do it other way, this would be much simpler and clearer way to do it. And I suppose it is quite common task not only for me. Currently 99% of my programs are in python 2.7. And I started to use python 3 only for tasks when I want to process unicode strings (ironically only to get rid of unicode).
