Hello,
I have several CGI scripts that I would like coordinate via a "First In / First
Out" style buffer.That is, some processes are adding work units, and some
take the oldest and start work on them.
What is the right way to do this?I suppose I could use an SQL server or
SQlite , but

Hello,
Imagine the relationship between an Ice Cream retail store and the several
manufactures that supply it's flavors.
The retail store has a single list of flavors and any given flavor can be made
by one or more manufactures. (Most are made by several.)

Hello,
I have some CSV data from Office / OpenOffice in "nearly ASCII" format. This
is just basic text but it it stored as UTF-8, and has curly quotes, etc.
Is there a way to easily read the file as ASCII by forcing these to the
standard ASCII equivalents?

Hello,
I have a list of tasks/items that I want handed off to threads/processes to

Hi,
My code looks like this:
for item in bigset:
self.__sub1(item)
self.__sub2(item)
self.__sub3(item)
# the subX functions, in turn, use various 3rd party modules.
Now, I would like to do this:
for item in bigset:
try:
self.__sub1(item)
self.__sub2(item)
I seem to be having an issue with __getattr__() being called even if the

Is there a typo somewhere, or I do i misunderstand things?

Umm... well. obviously I left out an __setattr__() call..
sigh.

Generally, though, trying it a second / third will work.
Is there clean way to write this on Python?

Thank you for all the great tips... I'll try a few and see what works.
I must say that I'm a bit surprised that the Python Std library does not have a

Hello,
I have code that looks something like:
self.aString = "abc123xyz"
self.theNumber = int(re.search('(\d+)',self.aString).group())
Is there a more Pythonic way of doing this? (Both the reg-ex and the Int

There seem to be many options...

simplest way to run external commands !
import os

os.popen(cmd)
my cmd is just an example, use any cmd you want & its output will be displayed
to you.
