The 's' replaces just one House match at any given time though the 's+' replaces The complete House sequence at once with the 2nd parameter.
In this case, it would make no distinction, because you are changing everything using an vacant string (although It could be better to utilize s+ from an effectiveness standpoint). In the event you have been replacing that has a non-vacant string, The 2 would behave in another way. Share Improve this solution Comply with

The width will not be laid out in the format string, but as an additional integer benefit argument preceding the argument that has to be formatted.
If the value to become output is less than 4 character positions wide, the worth is right justified in the sector by default.
If the value is larger than four character positions vast, the sphere width expands to support the appropriate amount of people.
So the very first if statement interprets to: if you have not handed me an argument, I'll inform you how it is best to move me an argument Later on, e.g. you'll see this on-screen:
