As Simon says, ask whatever questions you want.

Yes, except that you're relying on show() not returning a value there.
If show() was written so that it happened to have a print statement as
the last thing in the sub, then you'd get random 1s in your output.

That's a style difference, though, not a language capabilities issue.
