That said, if pathlib is not really 'for' file system operations, or
only handles some of such (and not other(s) that I would like), then
I'll happily go back/go elsewhere; and the great thing is that we are
free to make up our own minds and to do things differently from
each-other, if we want. ie YMMV!
I've learned a lot from this discussion. Thanks!

Python has a wonderful philosophy, that its "for" loop is NOT a means of
counting repetitions from 'here' to 'there' eg zero?one to 10. It is a
superior (IMHO) piece of language-design: a for-each construct. It is
nicely illustrated as: for each element in a list, do 'something'.
Accordingly, this perhaps-venerable ComSc problem is not helpful when
learning Python, even if Python will (happily) solve said problem!

nce/class release the GPIO pin, or is there another/a better way?
I haven't started to 'play' with my recently-purchased SoC, but forty
years after constructing my own Motorola D2 Kit (which gave me a
'computer' with binary inputs and bar-LED o/p), and much wanting to get
back to systems-on-a-chip or "microcomputers", even if (only) as a
hobby, I'm finally 'getting there'...
So, I'd like to request further clarification:
- do we need to 'release' (reset, or whatever) the GPIO pin, or
- are we talking about 'disposing of' a variable which represents/holds
the GPIO pin's value (as it was when 'read') - presumably in preparation
to reading it again/next time?
There is also a major implication here (which has been addressed as the
different behavior of del()/GC within different Python implementations).
Which Python are you using, under which OpSys - and if you are talking
about developing in Python on a desktop, will that carry forward to the
SoC or are there (material) differences in Python and/or OpSys?
I've been noting various contributions to this list, on topics related
to Python on/for SoCs. One of which is that there is a (at least one)
specialised version (?sub-set) of Python for SoCs. NB I haven't
read/done anything much further than that! You may like/need to
investigate...
Given that we are no longer talking about "How do I import a class...",
perhaps starting a new post with significant key-words in the Subject:
might encourage SoC-experienced folk to offer more knowledgeable
assistance...

see some languages have the option to generate warnings when the two strings
are on the same line. I wonder if a Python lint does that. It may at least
warn of this usage in time to check the code and put back the comma.

e you have more
complicated checks. Mine was only a suggestion to introduce the simple
C switch-case in Python, for making easier trivial if-elif chains and
for code optimization (C switch-case is optimized by C compilers)

convenience is in some sense removing a mathematical symmetry,
but so what?

I could
decide to use "dn_was_here" and the interpreter will be perfectly happy
- but because you don't expect it and would be made to (unnecessarily)
comprehend, I doubt it would promote our friendship/mutual-respect!

Should __new__() and __init__() break with convention because its/their
method/function signature is (really) part of the class's signature, and
thus there's a need for proximity?
(aka is "expected")
