How to find number of CPUs on a computer using Python?

Question

Is there any Python function to find how many CPUs are there on my computer?

Answer 1

You can use either multiprocessing or os module of Python to find the number of CPUs on a computer. 

Here is an example: 

>>> import multiprocessing

>>> multiprocessing.cpu_count()

8

>>> import os

>>> os.cpu_count()

8

>>> 

The number shown above is the number of logical CPUs available on the system. If hyperthreading is enabled on your CPU, the count will also include virtual cores.
