just a correction for my comment above, I should have written "Brython feels like a Python interpreter", but it's transpiling to JS too, the difference is that it's done directly in the browser (it's also possible ahead of time from CLI), and then the JS is stored in indexecDB (this can probably be compared to .pyc from CPython). It's explained there for the curious: https://github.com/brython-dev/brython/wiki/How%20Brython%20works https://github.com/brython-dev/brython/wiki/How%20Brython%20... edit: I've updated initial comment.
