Submit your ideas for questions for the Python Quiz for the Portland Python
Meetup next Tue, Apr 10, 2012, 6:30pm, Urban Airship).  Most anything
Python-related is fair game, any level of difficulty.

Email your quiz suggestions to me, rbednark at gmail.com, or use this form:
http://goo.gl/ujoEy  Submit your suggestions before 3pm Tue, Apr 10.

I will also be facilitating Reverse Q&A / Ask The Audience.  This is your
chance to ask questions of the audience (advice, problems, poll the
audience, ...).  If you're not going to be at the meetup and want to ask
something, email me or use the above form (http://goo.gl/ujoEy).  Some
example questions from past meetups:
  What is the clear winner among the Python web frameworks?
 Is anyone using PyPy in production?
 What do like and not like about Python?


Here's my notes from the last three Reverse Q&A / Ask The Audience sessions:

Q: What do you like about Python?
   - reads like psuedocode
   - __metaclass__

Q: What do you not like about Python?
   - too slow
   - GIL (Global Interpreter Lock) - not truly multi-threaded
   - live debugging tools awkward; not powerful
   - lambdas (it's only one expression; not a real anonymous function
compared to other true functional languages)
   - fragmentation of the web platforms (webpy, django, pylons, zope)
   - BDFL (led Python into the woods) (lamdbas, GIL, Python3, ...)
   - Python3
   - lot of lib maintainers have not chosen to go to Python3 yet
   - no case, "x if something else y"
   - variable scoping is weird
   - subclassing, overriding, super, keyword args -- lot of syntax; awkward
   - don't like spaces preference over tabs
   - loop - repeat - extra expressions before you hit the repeat section;
initial value; increment; loop/until/repeat (Databasic on Pick OS)
