Hi

Is it possible to renice the python process executing the current python
script ?

(untested)

I don't know if windows has the concept of renice...

On UNIX:>>> import os

Hmm. That seems to be the hard way, since you can set the nice value
of the current process (almost) directly:

import os
nice_adder = new_nice - os.nice(0)
os.nice(nice_adder)


But I suppose it could be useful in situations where you need
privleges you don't currently have. E.g.:

os.system("sudo renice -n %s %s" % (new_nice, os.getpid()))

Suspect one would need some combination of

win32process.SetPriorityClass(process_handle, priority_class)
and
win32process.SetThreadPriority(thread_handle, priority)

Note that with os.nice you can only *decrease* priority. For increasing
priority you need to run;
os.system("sudo renice -n %s %s" % (new_nice, os.getpid()))
or simply set the nice level when you run python in the first place (you do
also need sudo for this):
sudo nice -n -15 python myScript.py
