The scheduling priority to assign to the process.
Attempts to set the scheduling priority for the process specified by pid. Ifpid is not provided or is 0, the process ID of the current process is used.
The priority input must be an integer between -20 (high priority) and 19(low priority). Due to differences between Unix priority levels and Windows
priority classes, priority is mapped to one of six priority constants inos.constants.priority. When retrieving a process priority level, this range
mapping may cause the return value to be slightly different on Windows. To avoid
confusion, set priority to one of the priority constants.
On Windows, setting priority to PRIORITY_HIGHEST requires elevated user
privileges. Otherwise the set priority will be silently reduced toPRIORITY_HIGH.
