I'm not sure that it's a good idea to change os.cpucount(). I suggest to add a new function instead. os.cpu_count() iss documented as: "Return the number of CPUs in the system." https://docs.python.org/dev/library/os.html#os.cpu_count By the way, the documentation adds: "This number is not equivalent to the number of CPUs the current process can use. The number of usable CPUs can be obtained with len(os.sched_getaffinity(0))"
