## Simple demo of a rospy service that add two integers

# import the AddTwoInts service
from rospy_tutorials.srv import *
import rospy 

def add_two_ints(req):
    print("Returning [%s + %s = %s]" % (req.a, req.b, (req.a + req.b)))
    return AddTwoIntsResponse(req.a + req.b)

def add_two_ints_server():

    # spin() keeps Python from exiting until node is shutdown
    rospy.spin()
