In many contexts "hash table" is shortened to "hash" when there is no
ambiguity.
Dear Stefan!
So: may I don't understand the things well, but I thought that parser
drop the "nondata" CRLF-s + other characters (not preserve them).
Then don't matters that I read the XML from a file, or I create it
from code, because all of them generating SAME RESULT.
But Python don't do that.

In the multiprocessing module, on a Process p, by just doing p.daemon=1
before p.start(), we can make the child die when the parent exits.
However, the child does not die if the parent gets killed.
How can I make sure the child die when the parent gets killed?

Is it possible to automate the Python installation on Windows using
the MSI file so it does not add a Start Menu folder? I would like to
push out Python to all of my office workstations, but I'd like for it

I'm in the process of learning Python. I already can code
objet-oriented programs with the language. I have in my hands the
O'Reilly book by Mark Lutz, Programming Python, in two versions: the
2nd Edition, which covers Python 2, and the 4th edition, which covers
Python 3.

To explain my reasoning, this scheme will allow me to run the script three
ways, as shell, as one-shot CGI or as a persistent mod_wsgi module.
So to be more exhaustive:
In __init__ I can say:
import Grid
self.Grid = Grid.Grid
self.Grid is now the instance of Grid inside the module Grid.

If you are writing your own scripts, I would recommend Py3 for learning. But if
you are studying existing scripts to learn, Py2 might be better.
I have been doing Python for about 2 years and started learning Py3 with no
regrets. Py2 is not going to be "obsolete" for quite a while. It is almost

I never said there were no plans, but at $2567 out of $60k, I don't see
it happening soon. Unless someone decides to donate a huge sum of money
I accidentally quoted the wrong figure. I meant $4369 of $105000.
