Oh yeah. My favorite (and only) plugin so far is the https://github.com/twibiral/obsidian-execute-code

Let me explain: Obsidian is basically a very fancy wrapper around a folder with markdown files in it. (which makes it git compatible, which is one of the upsides). In Markdown, you can define codeblocks, with syntax highlighting, because of course you can, programmers will improve their own tools first. Now, there are two cases when you would do this:

1. you want to execute the code because it's actually driving something. Like some kind of interactive, "this is the manual, but also, you can just do it right away by executing this code" and then they give you the code.
2. you're actually building it as a document, and you want something in your document that is actually the output of some program that's producing some output. Like... analyzing numbers and creating a graph. You can now just put the code in the document, hit "execute" and you get your output in the document right then and there. And that concept isn't new, it's what "jupyter" also does, but jupyter uses a weird bytecode, xml zip format or something, in obisidian, because of the markdown base, it stays just code. (which again, makes it git compatible where jupyter isn't) AND you can do it not just with python but with...
