Hi,
I'd like to make sure, that a certain python program will only be run
once per host. (linux/windows)
so if the program is started a second time it should just terminate and
let the other one run.
This does not have to be the fastest solution, but it should be reliable.
I have a few ideas,

I've got a subclass of fractions.Fraction called Value; it's a mostly
trivial class, except that it overrides __eq__ to mean 'nearly equal'.
However, since Fraction's operations result in a Fraction, not a
Value, I end up with stuff like this:

where x is now a Fraction, no

Hello all,
I am trying to make a gui out of xrc and wxpython, but I think my
understanding of Python's class/method structure is causing problems.
The below code returns an error on the line

The error goes back to wxPython itself and says "attribute error:

m=(('as',3), ('ab',5), (None, 1), ('as',None), ('as',6))
and I need to build a "d" dict where each key has an associated list
whose first element is the count, and the second is the sum. If a 2-
