I am making a random name generator, it will pick two or three words
from a list and turn them into a name. It seems a database needs to
work with name/value pairs, so am I right in thinking for a simple
list, seperated by line breaks, a file is the most sensible choice ?
If so, what happens if someone else tries to write to the file whilst
I am working with it ?

Peter Norvig's creative thinking triggered renewed interest in PEP 289.
That led to a number of contributors helping to re-work the pep details
into a form that has been well received on the python-dev list:
http://www.python.org/peps/pep-0289.html
In brief, the PEP proposes a list comprehension style syntax for
creating fast, memory efficient generator expressions on the fly:
sum(x*x for x in roots)

A little annoyed one day that I couldn't use the statefulness of
generators as "resumable functions", I came across Hettinger's PEP 288
(http://www.python.org/peps/pep-0288.html, still listed as open, even
though it's at least a year old and Guido doesn't seem very hot on the
idea). I'm not too sure of its ideas on raising exceptions in
generators from outside (although it looks like it might be convenient
in some cases), but being able...

I'm attempting to turn some process than uses callback to return result
into a more user friendly generator. I'm hitting some road block so any
pointer would be appriciated.
Let say there is an existing method producer(x, cb). It calls the supplied
cb() every time when there is data available. The definititon of cb should
be:
def cb(data)

I have questions about thread safety in the 'random' module.
When using the random.Random class (be it Mersenne Twister or Wichmann-Hill
based), is it sufficiently thread-safe (preserving entropy and guarding
against attack) to just have each thread work with its own random.Random
instance? Or do I need to wrap my calls to each instance's methods to use
locks? Wichmann-Hill in particular has the warning in its .random()
vulnerability; do...

Hello all,
I'd like to probe the community for some insight, if I may. I am in the
planning stages of developing an XML generator for my workplace.
Our site has an internal news system which stores news items as
database entries. Our head organization has requested that all branches
make an rss or xml file available for syndication on their central news
site. I'm curious as to what plan of attack would be best suited for
this...

SQL Injection Attack
A database is a collection of information organised in such a way that allows computer programs to access data (even large amounts) quickly and easily. Data within a database is organised into tables, which contain records/rows of fields. A field contains the actual data used by the program.
Relational Database Management Systems (RDBMS or sometimes just DBMS) allow users the ability to access and manipulate data within...
