[Tutor] DATA TYPES

As I understand it python is not a strongly typed language so no declaration
of variables is necessary. My question is this:
If I use a variable in a program that stores certain numbers and I'm porting
it to say ... java where I must first declare the variables before I use
them how do I find out what type to give that variable, specifically is
there a way to identify the type of a variable used in a python program for
reference?
What I'm saying is if I have used a certain variable to hold literally
dozens of different values and I BELIEVE them all to be integers but I'm not
entirely sure that I have not stumbled into the float realm is there a way
to have python list all variables contained in a program and tell me what
type it has internally stored them as? I realize I could trudge through the
entire 1000 lines and check all the variables and see what values I have
assigned them one at a time but I'm wondering if there is an easier way to
get that data?
Thanks
Toby

Well that is the problem. Now you have to fix it. The proxy comes either
from the environment variable HTTP_PROXY or from the Windows registry, I
think it is the proxyServer value of the key
Software\Microsoft\Windows\CurrentVersion\Internet Settings
but I'm not on Windows and this is no longer a Python question so that
is as far as I will take it.

We need more information. Is this a GUI application? If so which GUI
software? Or are you trying to control the mouse in another application?

if an event happens.

Sorry but that does not help at all. I guess you want a character-based
console window and ability to respond to user keystrokes. If that is the
case use the curses module.
If not please explain your situation in more detail.
And in future questions please give the relevant details in the original
posting. Discovery processes like this are costly to everyone involved.

I do not know of a python library to do this.
Therefore, I'd use a popen call to

When I executing a program external to the main program in a thread,
and that thread hangs, can the thread be terminated?
How does one handle this situation?

Please define "hangs".
AFAIK that could mean waiting on an external event / signal /
communication that never happens, or running in an "infinite loop". So
which is it or is it something else?

Sorry. I don't understand that, so I can't help. Perhaps someone else can.

I presume he means he defines "hangs" as "waiting on an external event
/ signal / communicaiton that never happens".
AFAIK, there's no good way to kill a thread (google for 'python kill
thread' for lots of hits). IME most blocking operations have optional
timeout parameters, so you could restructure your main thread loop to
wait->work/timeout->repeat, which should make it easier to end the
thread.

Instead of using a thread, you could see if you could use a second
process. For instance, the following would work on windows (and is
killable).
import subprocess
import win32api
class SpawnController(object):
def __init__(self,cmd):
self.cmdline = cmd
def start(self):
self.process = subprocess.Popen([self.cmdline])
def stop(self):
win32api.TerminateProcess(int(self.process._handle), -1
