How to find out the number of CPUs using python

Question

I want to know the number of CPUs on the local machine using Python. The result should be user/real as output by time(1) when called with an optimally scaling userspace-only program.

Answer 1

For finding the number of CPUs which are using Python you can simply use:-

import multiprocessing

multiprocessing.cpu_count()

Another thing you can do is use the psutil library, which always turns out useful in these situations:-

import psutil

psutil.cpu_count()

This will work on any platform supported by psutil(Unix and Windows).
