You have my sympathies.
Most of what help you'll get here is 'inside-out':
Start with small toys. Work slowly towards more realistic problems
Many people (like you) would like to go the other way --
Start with trying to solve a real problem.
Handle the small nitty-gritties as they arise.
On and off Ive expressed a need in a similar direction eg
The problem with your approach is that its very system-specific
[1, 2, 3, 4]
will be the same on any python. Any OS. Any version.
However installing a package will vary.
And the best way of installing will vary widely.
So its harder to help
OTOH I will say this:
Any learning requires some faith at least temporary and provisional.
If you pick up some book which purports to educate on some subject
and decide before opening it that
- subject is bogus
- author is a rogue
you are not likely to get much out of it.¹
So it may irritate you to listen to the advice you get here to
start baby-steps first.
However if you dont listen, you are wasting time - most of all your own.
¹ Of course your suspicions may be true. Thats the fun of life!
