I was looking at Python 2.4 subprocess.Popen. Quite nice and handy, but I
wonder why a "kill" method is missing. I am just adding it via subclassing,
class Popen(subprocess.Popen):
def kill(self, signal = SIGTERM):
os.kill(self.pid, signal)
but I would prefer to have it in the standard Popen class. I am surprised
it is not there. Any comments?

Likely this is at least part of the answer:
c:\>python
Python 2.4 (#60, Nov 30 2004, 11:49:19) [MSC v.1310 32 bit (Intel)] on
win32 import os os.kill
Traceback (most recent call last):
File "<stdin>", line 1, in ?
AttributeError: 'module' object has no attribute 'kill'
Note the "on win32" part above...

Probably because it is not entirely portable. If you want a more
complete, but Posix-only (at least Linux and FreeBSD), process
management and spawning then you can use the proctools module in pyNMS. http://sourceforge.net/projects/pynms/

I forgot to mention that the pyNMS package also has a module called
"expect" that works like the Expect language. You can interact and
control interactive processes and external CLIs with it.

[Peter, noting os.kill is absent in win32]
Note, for the record, however, Jimmy Retzlaff's excellent recipe
for Win32 process termination, which can work with ctypes or
pywin32, and with either the PID such as popen returns and
subprocess.Popen stores, or the "handle" that spawn returns
(and which subprocess.Popen stores in its _handle attribute): http://aspn.activestate.com/ASPN/Coo.../Recipe/347462

Seems like an ommission, but probably due
to windows implementation problems?
Note my subprocess.py that was referenced
in pep 324 does have a kill method: http://www.pixelbeat.org/libs/subProcess.py
Note also that it also kills any children
of the subProcess using process groups.
