Sounds good. I don't use either of those. Do they allow/enable the 
execution of a single statement, eg a single 'cell' within a Jupiter 
Notebook?

There's quite a choir singing that song! Remember though, PEP-8 is 
specifically for PSL contributions (although it is useful within the 
wider community), also recall what the 'Zen of Python' says about 
"hobgoblins".

It is probably (close to) heresy, but if you are investing a lot of 
energy into learning Python, perhaps some of these other things fall 
into the category of 'nice to have' - until you're reading for added 
challenges?

Correct.
You may be able to do this with the aforementioned tools - I don't know. 
Some people use a debugger - but once again, it's more to learn before 
you even leave the starting-line. So, I'd recommend the most basic tool 
that comes with/as Python: running "python3" from the cmdLN.
