After saying I dropped my request, short replies keep coming.
Let me reply in this context:
Would there be BUILT-IN tools that can be expected to already be everywhere
which can be used at the top of a program you write and distribute to
quickly check if the rest of the program has the resources it
needs to run probably.
I am not currently planning on designing or implementing anything. It was an
academic question.
I was thinking along the lines of slightly advanced ways functions can start
with a group of assertions testing what is expected and quit if not set
right. They use assert().
Some of what is being suggested may have useful pieces you can use in doing
something like this. But I note that the ability to package things is not
something most users need. You need a kernel of guaranteed software you can
count on in order to test if other required elements and conditions can be
met.
Realistically, there are so many variations on python and how you can get
copies distributed that I cannot assume that if I write a routine that uses
numpy or pandas, as I have been doing, will be installed before a user makes
use of the software. And, you can even build your own versions of python
while leaving out or including things. It is nice to be flexible. But then
you may need to stock to some version from prehistoric times using
relatively few features AND being careful to not use features that were
later changed or removed.
Why bother?
OK, here is the solution. At the beginning of the script put out a big
warning telling the user that if they do not have all the required software
they are proceeding at their own risk and take full responsibility if
something weird happens before the software dies. Hitting ENTER will be
considered acceptance of the terms!
Again. Dropped. Moving on.
If the goal here is to tutor, no need to share complex solutions but rather
help students learn how to look at their problems and see what kinds of data
and logic to apply in what order and then how to debug the inevitable
mistakes like a missing comma.

If so, then also worth looking at the pipfile and pipenv which are aiming to
improve on the experience.
