Some help with my first python class and importing ....im making a lidar program

[jttolleson]

well, I have been learning a lot.... at first i new nothing about serial communication in python now i am learning more....

this is the actual answer, not the whole code to my question about, well, now, importing.

from sensor_msgs.msg import LaserScan
import laser_geometry.laser_geometry as lg   #i had some difficulty here.....
from laser_geometry import LaserProjection     #much more here
import sensor_msgs.point_cloud2 as pcl2          #glad it is resolved some

msg = laserscan()  # return value msg from laserscan()
lp = lg.LaserProjection()  # make lp out of modules
pointcloud2 = lp.projectLaser(msg)  #use lp to get a pcl from scan
pointlist = pcl2.read_points_list(pointcloud2)  
print (pointlist)
