I agree completely: sample/demo code should be the best you can make it. And I'm sure the Brython authors would welcome a pull request that improves their demo code.
But the comment I replied to was a bit misleading (no doubt unintentionally): it made two quite valid complaints about coding practices, without mentioning that these are only in the demo code.
When I read that comment I thought, "WTF? Brython injects a magic 'ctx' global into your Python code?" It doesn't, so I thought it was worth pointing out that these are just sample code issues that wouldn't affect any code you write in Brython.
