Thanks. Sounds like good advice. BTW, I just did some advertising on the
AstroPy NG a moment ago for your books. A query for good Py books.

Another question on similar matters. If I write a program and "compile" it for

the the compiled program is free of such restrictions. That is, it's an
independent program. I would like to think that if I've been testing it
successfully in IDLE, that the compiled version will produce everything I see in
IDLE.
Never ever, ever, test anything for distribution inside an IDE!
Always test it as it will be run - from the OS prompt or filemanager.
IDEs can introduce subtle differences of behaviour that conceal bugs.
Similarly never ever do a final test with debuggng code switched
on or the debugger active, again the debugger can cause subtle
changes in behaviour.
For example, when I run it in IDLE, and make a connection to the (camera)
h/w, a dos-like window appears that I otherwise never see. The program
purposefully either sends warning and error messages there through some built-in
facility or creates that window somehow. I'm dealing with tkinter in the app
code. I didn't write the (1600 line) program, but certainly am modifying it.
Do you run it with python or pythonw, that might also make a difference.
HTH,
