Interesting - - - - ". . . see if it runs." - - - that's the issue!
When the code is accessing sensors there isn't an easy way to
check that the code is working until one has done the all of the
physical construction. If I'm trying to control a pulsation system
using square waves with distinct needs for timing etc I hadn't
seen any way of 'stepping through the code' (phrase you use later).

I have been following this list for some time. Don't believe that I've ever
seen anything where anyone was referred to 'Idle'. In reading other user
group threads I have heard lots about java and its ide - - - don't remember,
again, any re: an ide for python.
Even in maker threads - - - say for arduino - - its 'use this cut and
paste method
of programming' with no mention of any kind of ide when it was microPython - -
although being a subset of python it Idle may not work with it.

That was the plan.

My problem is that I'm needing to move quite quickly from 'hello, world' to
something quite a bit more complex. Most of the instruction stuff I've run
into assumes that one is programming only for the joy of learning to
program where I've got things I want to do and - - - sadly - - - they're
not sorta like the run of the mill stuff.

Oh well - - - I am working on things!

Thanks for the ideas and the assistance!

You use a hardware debugger then ... and if you're talking hardware,
chances are you're also not talking Python (yes, yes, I know
"CircuitPython" is a thing, or was it MicroPython?)

Bearing in mind, of course, that "Arduino" is basically "Programming for
dummies" level of stuff usually (i.e. people just getting their feet
wet). It's meant to be a relatively "easy" introduction for students /
hobbiests / non-programmers into the world of programming for
microcontrollers.

Sounds like you've been reading instructables :)
