How to deliver instance of object to instance of SocketServer.BaseRequestHandler? | 711,002 | <p>This is problem.
My primary work is : deliver "s" object to "handle" method in TestRequestHandler class.

Is it possible to get a timezone in Python given a UTC timestamp and a UTC offset? | 712,322 | <p>I have data that is the UTC offset and the UTC time.

The more information is typically the location to which the time applies - which country, or state, or city.</p>

How to execute an arbitrary shell script and pass multiple variables via Python? | 714,360 | <p>I am building an application plugin in Python which allows users to arbitrarily extend the application with simple scripts (working under Mac OS X).

Turning ctypes data into python string as quickly as possible | 714,367 | <p>I'm trying to write a video application in PyQt4 and I've used Python ctypes to hook into an old legacy video decoder library.

What is a maximum number of arguments in a Python function? | 714,475 | <p>It's somewhat common knowledge that Python functions can have a maximum of 256 arguments. What I'm curious to know is if this limit applies to <code>*args</code> and <code>**kwargs</code> when they're unrolled in the following manner:</p>

def do_something(*items):
