Run your program

Run the file you are working on and read what your program prints back.

  1. Press Run

    Run starts whichever file you are looking at. The first time you run a language, Warsha downloads it once — Python, Java — and after that it starts instantly, even with no internet. If a program runs away with itself, the same button becomes Stop.

    The Run button in the editor tab strip, highlighted.

  2. Read the result

    Whatever your program prints appears in the console below. When it finishes you see a line with its exit code; red lines mean something went wrong along the way.
