FYI you could pyScript.addEventListener('mpy:done', () => pyScript.remove()) instead

this might be helpful, we use codedent which might simplify writing code in JS for your demos ...

import dedent from 'https://esm.run/codedent';

dedent`
  def this_is_fine():
    return "fine"
`;

/**
def this_is_fine():
  return "fine"
*/

You can then write cases like:

const options = {
  1: dedent`
    import sys
    print(sys.version)
  `),
  // ...
};

maybe worth using it? it's pretty battle tested in PyScript itself (it's a dependency) + it uses template literal tag which feels "very meta" giving this context 😁
