It's caused by Python not wanting to send non-ASCII characters to your
terminal. To override this you need to create a sitecustomize.py file
in your /usr/lib/python/ folder and put the following in it:
import sys
sys.setdefaultencoding("utf-8")
This will set the default encoding in Python to UTF8 and you should
stop getting these parsing errors. I dealt with this recently when I
was playing around with some international data.

Re: [Tutor] Ptyhon GUI doubt
Hi Raj, I used to get this error sometimes when I was using Windows. Killing the Python process via Task Manager and restarting IDLE was enough to get me going but if it still remains an issue, you can run Python in single process mode, the following is snipped from IDLE help: "Running without a subprocess: If IDLE is started with the -n command line switch it will run in a single process and will not create the subprocess which runs the RPC Python execution server. This can be useful if Python cannot create the subprocess or the RPC socket interface on your platform. However, in this mode user code is not isolated from IDLE itself. Also, the environment is not restarted when Run/Run Module (F5) is selected. If your code has been modified, you must reload() the affected modules and re-import any specific items (e.g. from foo import baz) if the changes are to take effect. For these reasons, it is preferable to run IDLE with the default subprocess if at all possible. " On Mon, Aug 24, 2009 at 9:28 PM, Reddy Etikela, Rajasekhar wrote: > Hi, > > I am new to the Python.

For a long time I was switching between web frameworks, as each have their nuances which make them seem better than the others, and what you end up with is a bit of knowledge on each...but not enough on any single one to get the full power out of it. There is always risk involved with backing a single horse, but I found it massively beneficial when I did. In the end I settled with Pylons because I like it's lack of glue between components but I'm positive I could have done all of my projects in any of the frameworks and each would have had their challenges and successes. Kudos to Massimo though; web2py is a spiffy idea and it's implemented well. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Using the time module to extract a semi-random number
Hi Katt,
The following does the trick for me:
number = int(time.strftime("%S", time.localtime()))
There may be better ways to do it though.

Might be nice to mention to all who access these emails from work that
the site this script is scraping is not safe for work.
