This is the Python Users Group Berlin (PUB). We host presentations and discussions about Python and Python-related software development (mostly framework-independent).
Currently most talks are held in English language but we usually switch to German if all visitors speak German. Please indicate your interest on the mailing list (http://starship.python.net/cgi-bin/mailman/...) if you are interested in any specific language so the speakers can prepare for that. We meet every 2nd Thursday of the month at 7pm at co.up (close to Kottbusser Tor or "Kotti" ;-). Since attendance rate in Berlin is usually under 50% only we've stopped limiting the number of RSVPs. As we have space for 40-60 people at co.up the rule is: first come, first seated.
New: There is a new slack team for us named pythonberlin for which you can invite yourself here: https://pythonberlin.eu.ngrok.io (a service almost available 24/7, though, since it's running on a Raspberry Pi.).
You might also want to subscribe to our mailing list (usually in German) which has become rather low-traffic over the last years.
