Answer 1

Thanks, should not it work with any kind of iterables? Only with lists?

Answer 2

Tamás Berki I think map and filter should work for all builtin iterables, but I'll check whether there are any exceptions.

Answer 3

Try removing the first 2 print statements or swapping the last 2 print statements, very confusing, I can't explain this.
