Yes potentially, but you still need to mess about with process ids etc
to find which process to send the signal... And you would have to do
the two things in separate threads since system() blocks your main program.

look at the functions in the random module.

If I use popen2, I need to write to one of the tuple parts.
>>> f = os.popen2('ping 192.168.8.85 -c 100 > cap1.txt')
>>> f[0].write('\x03')
Thank command works, but 'f[1]' is in read-only mode and I can't write
to it.
My command in the background is still not terminated.
BTW I use Linux as OS.

Thats almost certainly because ping never reads its input.
In that case
With what can I try and see what the PID is when using popen() or popen2() ?
One thing that I noticed now is that when using popen() and the
sys.exit(). The command is completed before my Python shell is
terminated and if I use popen2(), sys.exit() works immediately but the

Aren't the odds just based on how many tickets you buy? The odds aren't
affected by different people buying more tickets. If only one person

As you say this has nothing to do with classes its more basic. Its about
namespaces. Try reading the namespaces topic in my tutor for more info.

this looks like it'll also accept invalid data, such as "1/" ... i
think there's some more tweaking involved to get it so that if there's
a '/', there is at least one digit afterwards.

Your issue is not so much with classes as it is with namespaces. You'll

Hi Nick,
Global variables in Python are global for *reading*, based in the
precedence order for looking into the namespace: locals, globals(module
scope actually), builtins
for writing, as variables are created on the fly, a local variable will
be created and will mask the global one.
That's

as alan mentioned, it's all about namespaces. the "global x" you have
in the above piece of code doesn't do anything (because you're already
or still in the global [name]space).
