[Moin-user] Upgrade error: cannot import name wiki

[Gnarlodious]

After upgrading, a macro called EventCalendar.py does not work, I get
error "cannot import name wiki".

I see the script has not been updated for 3 years. Does anyone know a
fast way to solve this, or does the entire script need to be redone?
It looks like some module is no longer available. You can see the
error in realtime here:

Sorry, my Python is not that far advanced.
