I failed to follow the instructions from http://library.isr.ist.utl.pt/docs/ro... `1 #!/usr/bin/env python 2 # license removed for brevity 3 import rospy 4 from std_msgs.msg import String 5 6 def publisher(): 7 pub = rospy.Publisher('chatter', String, queue_size=10)` ......... I have a file name publisher.py and it has `float32 a float32 b float32 c` Should I do the following? But it doesn't work. What should I do so it pulls the data from publisher.py? `1 #!/usr/bin/env python 2 # license removed for brevity 3 import rospy 4 from std_msgs.msg import Float32 5 6 def publisher(): 7 pub = rospy.Publisher('topicName', Float32, queue_size=10)`
