You are welcome, I only learned of it a few weeks ago and it solves a lot of problems. It's still relatively new, so while jupyter notebooks / lab support, using it inside other editors with runnable code blocks is still a work in progress. VS Code looks to have an extension for previewing the markdown, but I dont think it can run python code blocks in it (for now).

I agree with you, RStudio's R Markdown feature was my favorite part about it, easily wrote my assignments for a statistics class with it.
