Slave Rotation by Script

[usc001]

Hello, 
im trying to do a simple Rotation Transfer using script operator.
I have a Dummy in the Scene with animated Rotation and id like to Transfer the Rotation to my Particle. 
I see in the Documentation that SetRot only work with Quaternion Values. 
Is there an easy way to translate the quaternion to an euler angle (i think thats what its called? 0-360 degree i mean).

So im basically looking for Resources to understand how this translation works. 
A simple script example on how to transfer a Dummy Rotation to a Particle would be very helpful!


Thanks in Advance!
