Python | os.sched_rr_get_interval() method

OS module in Python provides functions for interacting with the operating system. OS comes under Python’s standard utility modules. This module provides a portable way of using operating system dependent functionality.
OS module contains some methods which provides an interface to the scheduler and used to control how a process is allocated CPU time by the operating system. 
os.sched_rr_get_interval() method in Python is used to get the Round Robin quantum in seconds for the process indicated by the specified process id.
What is Round Robin quantum? 
In the Round-Robin scheduling policy, processes are dispatched in a FIFO manner but are given a limited amount of CPU time called a time-slice or a quantum. 
Note: This method is only available on some UNIX platforms.
 

Syntax: os.sched_rr_get_interval(pid) 
Parameter: 
pid: The process id of the process whose Round Robin quantum value is required. A pid of 0 represents the calling process. 
Return Type: This method returns an float value which represents the Round Robin quantum in seconds. 
 

Code: Use of os.sched_rr_get_interval() method 
 

# Python program to explain os.sched_rr_get_interval() method  

# importing os module 
import os

# get the Round-Robin time quantum
# of the current process
# A pid of 0 represents the
# the calling process 
pid = 0
quantum = os.sched_rr_get_interval(pid)

# print round robin time quantum
print("Round Robin time quantum (in seconds):", quantum)

Round Robin time quantum (in seconds): 0.016
