Hi there! I'm completely new to ROS and using kinetic. During practicing with nodes, i got an issue. In the code I attached below, I want to use the x variable from input() into ros.loginfo() but the error says that, the {input name} is not defined. How do I do it properly?

the node code is below:

!/usr/bin/env python

a must ; creating file in linux

import rospy from std_msgs.msg import String

rospy.init_node('input_trial')

x = input("what's your name?:")

while not rospy.is_shutdown(): str="Hi there %s" %x ros.loginfo(str)
