That _is_ backwards. What do you mean by "run"? The default behavior
in Ubuntu, when you double-click an executable script, is to prompt
whether you want to "display", cancel, or run the script. The default
behavior for a non-executable script is to open it up in your default
I'm guessing that you are using an IDE to write your Python, and when
you double click a non-executable file, it opens it up in the IDE, and
then your IDE executes it. When you double-click an executable file
on the other hand, it is simply executing it and exiting, too fast for
you to notice. Does this sound plausible?
Regardless, have fun with Python. It's an excellent language, and
generally a pleasure to code.

stand like dwarfs on the shoulders of giants.' The image was a
commonplace by the time Newton used it, his one contribution being to
erase any sense that he himself might be a dwarf."
