Microsoft's dev team for Python in Visual Studio Code updated its tooling to improve working with the language's interactive Read-Eval-Print Loop functionality.

This interactivity is known as REPL – Read, Evaluate, Print, Loop. The REPL alone makes MicroPython amazing for board bringup, building devices quickly, reverse-engineering, debugging device ...

But even when I was learning Python, for instance, the interactive mode didn't help me that much in understanding the strange result my method was returning; the debugger did.
