The central problem that I'm running into
The central problem you're running into is that you have a huge bark and no bite. Literally delusions of grandeur. I don't think you can even get past a "hello world" program on Python, let alone C++.
What I'm trying to do is to design a space simulator to journey to a space body and extrace Ice slabs that are close to earths atmosphere conditions or chemical composition and drop them in the Arctic Ocean.
What it is at the core is learning how to design circuit on the fly and interface with Python and )LCs, namely Arduino.
Even what you're describing here is delusionally avant-garde at best, and nonsensical at worst.
Like, is it a physical simulator cockpit type device where you for some fantastical reason need to "code on the fly" low-budget hollywood movie style?
Or is it a software simulation, sort of like a video game? If so, what does "interface with python and Adruino" mean in that context?
What you are trying to do would take a team of people at NASA with doctorates, or game devs with years of experience months or years to achieve and you're trying to do it sitting on a hammock with 0 budget, 0 skills, and 0 discipline? It's a massive feat. Why are you getting bogged down in the almost irrelevant minutia such as "but how to design two smaller crafts one for ice lab pickers, and one for atmosphere sniffers" when there are core concepts you have no hope of ever achieving? How are you going to code this simulator? How are you going to engineer the electronics and hardware? Focus on that shit first and get it done before randomly chatting shit about something insignificant that could only ever conceivably be decided/fixed/created AFTER you've done all the previous steps.
It's true, people do achieve some great feats by themselves, while starting from scratch... but that takes laser focus, discipline, commitment, and some bare minimum level of skill. You have none of these. Every month you have some grand undertaking, or some life-changing revelation which you beat your chest and bark about... but at the end of the day, nothing gets done, and you have nothing to show for it.
If you really want to learn coding (and I mean from scratch, like 5th grade level - because you really don't know a single shit about programming) and if you are serious about it, I can REALLY help you, by giving you one month cycles of learning material, which I will expect you to study, do homework on, and show a tangible project at the end of - then let me know. I will genuinely help you with that if you are truly serious about it.
This section isn't the journals section. It isn't for dreams and delusions, it's for serious discussion. If you're not going to actually be realistic here, then pack you shit and don't post in this section.
