running IDLE from another program?

[John Salerno]

If I want to write my code in a separate text editor (I like UltraEdit) 
but then press a single button to have that code run in the IDLE 
environment, is that possible? I know that you can configure UE to run 
external tools, but I can't figure out how to run IDLE this way, because 
when I check on its properties to find it's file path, it is just the 
Python directory itself.

So not only do I not know where to find the actual file to run IDLE (if 
possible), but I then don't know how to run my code in IDLE (again, if 
possible). I guess I could write a script or macro that opens IDLE with 
a new code window ready, copies and pastes my code from UE into this 
window, then runs that code, but that seems messy, if that would even 
work. And wouldn't it also prompt me to save the file before running it 
in IDLE anyway?

So it comes down to this: is it possible to run code (that was created 
in a separate editor) in IDLE in some kind of automated way?
