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. We meet every 2nd Thursday of the month at 7pm at co.up (http://co-up.de) (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 (http://co-up.de) the rule is: first come, first seated.
Event organizers, please note: As we receive too many messages asking us to advocate specific events we usually don't do that, except for very special cases with high relevance to the Python community. If you want to advocate your event you're kindly invited to show up at the next meetup in person and give a lightning talk (5 minutes) about it.
