One more thing, as a self-taught programmer, I struggle to understand other people's code. I would therefore like to read more about how programmers _inspect_ code so they may modify how it works. For example, let's say you find a third-party package (I'm using Python, so we call these modules), and you want to fork some particular package so it uses a database instead of config files. Now I get the general idea of what I could do--clone the code, start editing it, setting breakpoints, walking the code execution, and essentially rewriting making their code my code. But it's a tangled web, no? Not easy. And then there must be (?) shortcuts? Plus, I'd like to read about the terminology and methods so I can search for other people's tutorials.
