Python Get Number of Cores Using os cpu_count() Function

The easiest way to get the number of cores in Python is to use the cpu_count() function from the Python os module.

import os

print(os.cpu_count())

#Output:
4

The Python os module gives us many useful functions for interacting with a computer’s operating system to gather information and make changes.

One piece of information which can be very useful is the number of processing cores or CPUs that a computer has.

We can easily get the number of cores using the os module cpu_count() function.

You can print the number of cores in your system using the following Python code.

import os

print(os.cpu_count())

#Output:
4

If Python cannot determine how many cores are in your system, then cpu_count() will return None.

Hopefully this article has been useful for you to learn how you can get the number of processing cores your computer and system has using Python.
