[Geany-Users] Geany on Raspberry Pi... can't see Tkinter window

[Lex Trotman]

What happens if you run your script from the command line?  I suspect
it will just return the same as it does in Geany.  Geany runs things
exactly as if from the command line, so if your script doesn't run
there it won't run in Geany.

The other IDE is a specialist Python thingy which may be doing
something different, possibly helpful for beginners, but not so
helpful when you actually want your script to run as a separate
program independent of the IDE.

Cheers
Lex
