If you just open an HTML file in your browser via its local path (e.g. /home/user/...) the browser will prevent you from loading other files by JS due to CORS. So we need a web-server to set the appropriate CORS headers. Any web-server would do.

For inline code, yes it would be doable someone would need to continue https://github.com/pyodide/pyodide/pull/692

For examples, I'll respond in the Pyodide issue where you commented.
