how to get the data from subscriber

Question

Hi,

In python I have this:

self.cmd_vel_sub = rospy.Subscriber('cmd_vel', Twist, self.cmd_vel)

and I need to access the angular velocity of this subscriber. How can I do it?

I've tried:

self.cmd_vel_sub[1][2]

self.cmd_vel_sub.angle.z

But non work.

Thanks.
