Hi, I am trying to create a loop that performs a look up transform from a map to another frame. I am also trying to output this information on the terminal when the node is running. Everything is working fine. I am just wondering how I can log this information on the terminal when the node is running?

SOME IMPORTS

if name == 'main': rospy.init_node('TransformListener')

tfBuffer = tf2_ros.Buffer()
listener = tf2_ros.TransformListener(tfBuffer)

rate = rospy.Rate(10.0)
while not rospy.is_shutdown():
    try:
        trans = tfBuffer.lookup_transform('base_footprint', 'map', rospy.Time())
    except (tf2_ros.LookupException, tf2_ros.ConnectivityException, tf2_ros.ExtrapolationException):
        rate.sleep()
        continue

    msg = geometry_msgs.msg.Twist()

    msg.angular.z = 4 * math.atan2(trans.transform.translation.y, trans.transform.translation.x)
    msg.linear.x = 0.5 * math.sqrt(trans.transform.translation.x ** 2 + trans.transform.translation.y ** 2)

   # turtle_vel.publish(msg)

    rate.sleep()
