Were you thinking of get:
a.get(k[, x]) returns a[k] if k in a, else x
But do you want to lookup by the object itself, or by its val attribute?
(Your code suggests the latter, but that's not what your title says...)

Ok, I got it running. Thank you!
I removed the space and top of that I had foul indentation in return
statement.
I'll try the approaches you suggest.

Indeed. Any handle on the right object will do.

Sorry, that should have been a call to the .split() method of expr, i.e.:
tokenList = expr.split()

Thank you Stephane,
it is almost what I want.
I'm going to improve it a little and then provide the code back.
Where is the best place ?

He's already asked about numpy. He is stuck with 2.2.

Subject: How can I kill a running thread when exiting from __main__
Hi!
I have the following problem: I have written a short Python server
that creates an indefinite simulation thread that I want to kill when
quitting (Ctrl-C) from Python. Googling around has not given me any
hints on how to cleanly kill running threads before exiting. Any help
is appreciated!
Carl
### CODE EXTRACT ###
import pythoncom
class QueueThread( threading.Thread):
def __init__(self, command):
threading.Thread.__init__(self)
self.command = command
def run(self):
pythoncom.CoInitialize()
try:
object = Dispatch('application')
execute = getattr(object, 'Execute')
execute(self.command )
finally:
object = None
pythoncom.CoUnitialize()
queuethread = QueueThread("queuehandler")
queuethread.setDaemon(True)
queuethread.start()
## How can I kill "queuethread" when exiting (Ctrl-C)?

It looks like it can't find the command ld. Can you compile any other
extension
modules?

Subject: Extracting a file from a tarball
I am trying to extract one file from a tarball, without success. This is
the code I'm using to open the tarball and extract the file:
tar = tarfile.open(component+'-win32-app-'+bestVersion+'-dev.tar.gz', 'r')
extractedFile = tar.extractfile('symbols.xml')
And this is my error:
Traceback (most recent call last):
File "C:\CognosInstalls\AutoTest\PollDir.py", line 121, in <module>
main()
File "C:\CognosInstalls\AutoTest\PollDir.py", line 119, in main
extract('c:\\', 'I:\\daily\\'+components[i], components[i])
File "C:\CognosInstalls\AutoTest\PollDir.py", line 27, in extract
filelike = tar.extractfile('symbols.xml')
File "C:\Python25\lib\tarfile.py", line 1488, in extract
tarinfo = self.getmember(member)
File "C:\Python25\lib\tarfile.py", line 1171, in getmember
raise KeyError("filename %r not found" % name)
KeyError: "filename 'symbols.xml' not found"
I know that the tarball contants this file "symbols.xml" but I don't
understand why it's not extracting it. Any help will be greatly appreciated.
Thanks,
Emile Boudreau
