Changed resrun to print No result if the program did not output anything. Changed rescompil to always write No Compilation for Python.
Fixed rescompil for stderr in case of Python.

The rescompil variable is used to show output from stderr.
Reset the rescompil back to the original way of being blank, if there
is no output to show.
