Thanks for creating this wonderful tool!

Testing would be a wonderful addition; an alternative would be allowing multiple correct answers. Currently, if the correct answer is

def f():
  a = 1
  b = 2
  return a / b

then the valid answer

def f():
  b = 2
  a = 1
  return a / b

would be rejected.

Thank you for your feedback!

This repo is based on the js-parsons package that brings this functionality, and unfortunately, it is not possible there. Probably it's worth to how they are handling this case: https://js-parsons.github.io/

I hope to be able to change it to the parsons package from the Runestone project.
