Well gurus tend to die them also...

Ouch, you have us.

It is good to know a script language, I like perl very much.

If python solves your problem, it will be a much faster processing
the having no solution. At least you could build a prototype
implementation and test out the problem more quiokly than doing all
the nitty-gritty handiwork in C.

It's good to know ones best kind of learning, from what I heard, some
learn by seeing, some by hearing, and some by feeling (tactile).

Well it isn't that counting starts with zero, it is that to go to
number 2, you have to add one to number 1, soo think it more as an
offset than a count:

int arr[10]; // 10 is the count, the number of elements.

int start = arr[0]; // i.e. at offset 0 of arr, there is where start is
int end = arr[9]; // i.e. att offset 9 of arr, there is the end
int count = sizeof(arr)/sizeof(int); // this is a count, the number of elements

there doesn't seem to be any cpython for mcus available:
https://en.wikipedia.org/wiki/Cpython#Distribution

> Please advise


If you are at ease with python you are not going to do anything
advanced, why not just stick with micropython and use a mcu that
supports it.
At least you can start with micropython and if and when it fails
to deliver, try some other language.
In the meantime try out a few languages and see if they suits you.
