OK. Here's a workingish example, cut down from the link
I posted earlier. This one was designed to work with Win2K
which I was using at the time. For WinXP and later, there's
a new counter with the ungainly name of
Win32_PerfFormattedData_PerfProc_Process
which should give you the number straight off without having
to do the take-and-diff-and-divide dance. However, it doesn't
seem to do anything useful on my (XP) system. Haven't tried
that hard, I admit.
As ever, if you can find any example around the Web -- and there
are loads -- converting it to Python should be a breeze.

import time

c = wmi.WMI ()
process_info = {}
while True:
for process in c.Win32_Process ():
id = process.ProcessID
for p in c.Win32_PerfRawData_PerfProc_Process (IDProcess=id):
n1, d1 = long (p.PercentProcessorTime), long
(p.Timestamp_Sys100NS)
n0, d0 = process_info.get (id, (0, 0))
try:
percent_processor_time = (float (n1 - n0) / float (d1 - d0)) *
100.0
except ZeroDivisionError:
percent_processor_time = 0.0
process_info[id] = (n1, d1)
if percent_processor_time > 0.01:
print "%20s - %2.3f" % (process.Caption, percent_processor_time)
print
time.sleep (5)
