G'day :)
I started getting sick of reading tutorials so for a bit of a break I set
myself the task of writing a program to pick lotto numbers, 6 numbers
between 1 and 44 (inclusive). I had done this many years before in basic and
I thought back then it would be a simple task but I struck a

Hi,
Just poking at threads, I'm contemplating doing something that I think
may be a very dumb thing to do, or it may work fine.
In the following code -

import Queue
import reg
import msvcrt
class ParseThread(threading.Thread):
def __init__(self, Q, parser):

book

PDF syntax is, I believe, a subset of Postscript. Postscript is a
page description language so it defines a document something
like a programming language draws graphics. Lots of positioning

Calling it a bug is a bit harsh when it's documented that way :-)

that / is (approximately) the inverse of * and % is "remainder after

Do you need to use copy and paste?For instance, say all your
functions are in a file called "factorization.py".In IDLE, you could

It's not listed in the math module.

Because that's the way Guido designed I guess. ;-)

You can always use parentheses, and if in any doubt should
do so.

I pasted the function subroutines, one at a time, into the shell, and

I'm not sure why you are copying the code into the shell?

The easiest way is to use a single folder for all your code.
the folder called site-packages should be included by default

Hi Brian!
There are two functions for an file-Object which deliver the position in the
file
and can seek-function to set the offset in the file:
f=open(.emacs, r )
help(f.tell)
Help on built-in function tell:
tell(...)
tell() - current file position, an integer (may be a long integer).

The module name is factor30
no need for the .py, thats the file name. Two differemt things!
