I just ran into a curious behavior with small floating points, trying to find
the limits of them on my machine (XP). Does anyone know why the '0.0' is
showing up for one case below but not for the other? According to my tests, the
smallest representable float on my machine is much smaller than 1
Hi Danny,
Thanks for the advice.

G'day Tutors,
I watch many different TV shows on my PC, as many of us do. But I am
sick and tired of forgetting which episode I was up to. So, in a
prodigious effort to avoid ever using, say, a pen, I am working on a
script to take over some of my brain's memory handling. When complete,

Hello,
My name is Guy and I live in San Francisco, I would like to learn python
ASAP and am looking for a tutor.
I know there are many sites out there that can help me self learn it but I
am out of a job and it looks like if I learn Python as a scripting language
I could speed up the process :-)

Yup. *grin*
Do one more thing though: call the function something other than
'printFood' now, since it clearly isn't doing any printing
I get it! Have printFood return a string!
def printFood(self):
return self.food.foodName
Now I don't get the weird output anymore!

Hey Chris, check out this version.

self.name = name

Hi Chris,
I'm going to be a little insidous and bring some ideas from the textbook

Here is some code I wrote:
class Food:

Food.foodName = name
class Customer:
def __init__(self,name):
Customer.name = name
Customer.food = 0

Yeah, looking over it right now as a point of fact.

Hi Nephish,
Have you had a chance to look at the 'struct' module yet?

Since this is a homework problem, we're limited in what we can say here.
Can you simplify the problem a bit? Can you write a program that asks for
stars, and just prints out that many stars? That is, ignore for now

The simple mechanical error is that when you're substituting more than
one value, you need to wrap the value list in parens:

what you want here is 'self.name = name' then in your code later you can do:

Maybe somebody has an idea or a tip as to what`s going on

Hi Kent,
To answer your first concern, not all changes need to be intercepted
by one the child thread. I have not given out all the details about
the program, but if the parent thread gets certain values from the
database, it will take actions that may affect the child thread other
than just by se
