If you found an issue in an exercise, or the website, please either:
See the sponsor page.
The Python community is known to be friendly and welcoming, don't hesitate to ask for help!
There's a Python forum at
discuss.python.org, feel free to ask
your question in the Users category.
You can ask in the #python channel of freenode, you can use
https://kiwi.freenode.net if you don't
have an IRC client.
There's the python-list mailing list.
Don't ask to ask, just ask.
Be polite and respectfull.
Don't ask for someone else to solve your exercise for you, it won't help you learn.
If you have the correction server connection error, there's two main possibilities:
Either your internet provider (or VPN, or ...) blocks WebSockets, in which case you should politely ask for them to update their blocking policy.
Or my server is down (in which case you should not even be able to read this message).
Anyway don't hesitate to open an issue in the bug tracker, so I know.
Ask me, I'll reply, and if it's frequently asked, I'll add it here.
You can ask me using by opening an issue, or send me an email: julien@palard.fr.
