I want to print the values of pitch, roll and yaw.
could you tell me how to print this event message please?

You can use :
drone_attitude = drone.get_state(AttitudeChanged)
print("pitch : " , drone_attitude["pitch"], "roll :" , drone_attitude["roll"], "yaw :", drone_attitude["yaw"])

thank you very much
