Inspired by the recent discussion on notebooks - https://news.ycombinator.com/item?id=22164916

I would like a Python setup a la RStudio. This means that:

- it works with unmodified plain text files - I don't want to use notebooks and I don't want cell magic (#%%) in my scripts

- at any point I can run a keyboard shortcut which executes the current line* of code

- if the cursor is on a part of a code block like the top line of a function definition or an if statement, the REPL is smart enough to figure out that I want to run the entire block of code

- after running, the cursor moves to the next line or to the line after the block that was just executed

- selecting multiple lines will obviously run all of them

- I don't need to insert an empty line at the end each block of code that I want to run (this is a problem with VSCode's "Send to terminal" option)

- selecting multiple lines allows you to run all of them of course

- the Python session stays live and can be inspected after the code finishes running

Open to suggestions about any editor/IDE/config file that can do this.
