this?

Thanks!

Hi all,
I'm trying to write a loop that will build a list of "template

My current implementation is *really slow*. It took 15 minutes to

Python seems to default to the main system IP for outbound connections
(such as urllib), but I want to bind to one of my other IPs for
outbound connections.
Any ideas?

Hi,
I have a cgi script where users are uploading large files for
processing. I want to launch a subprocess to process the file so the
user doesn't have to wait for the page to load.
What is the correct way to launch subprocess without waiting for the
result to return?
Thanks!

Hi all,
I was reading in the Beautiful Soup documentation that you should use

Since I'm already using Element Tree elsewhere in the project, I

I have a collection of ordered numerical data in a list. The numbers

Now that I look at it, I could probably take out the f.seek().
