for instrument control, you can use the PyVisa package
see: https://pyvisa.readthedocs.io/en/master/ to take a look.

As far as python version, you could use Anaconda, but before making your selection, I'd download and read (or at least skim): www.southampton.ac.uk/~fangohr/training/python/pdfs/Python-for-Computational-Science-and-Engineering.pdf
The package availability allows you to customize the standard python to suit your needs.

Image control packages are available

You may want to take a look at www.PyPi.org and skim some of the 160,043 packages available
Any one of these packages can be added to standard python with the following simple command:

pip install packagename

As for editor, etc, I would recommend (and a lot of moderators will join me on this) VSCode
which has pretty much everything you need available on demand.
Here's a tutorial on how to properly install: https://python-forum.io/Thread-VS-Code-f...ght=VSCode

but I feel I will learn much more by some project and not an exercise.

couldn't agree more. I think this is the way that I learned all languages, even after formal education.

I did a lot of instrumentation control (I'm retired now) mainly in the field of spectra-chemical engineering.
Couldn't use python at the time, it was free, so management decided it unsuitable. It would have made life easier.
