Could someone please explain to me what the brackets do again? I read the article but I just want to be 100% sure. for example: the pattern "%s%a+%s%w+" compared to "[%s%a+%s%w+]" compared to "[%s,%a+,%s,%w+]"

You use brackets for a set of identifiers. `[%a%d]` is matching either a letter or a digit, but of course it's unnecessary because %w exists.
