# What units does the rotation argument expect when creating objects?

I want to create a lamp in blender using python. I want to give the lamp some rotation. As per the documentation I can set the initial rotation using a tuple of numbers in the function call like this `rotation=(0.0, 0.0, 0.0)` this is the specifc documentation for the rotation parameter:

rotation: (float array of 3 items in [-inf, inf], (optional)) – Rotation, Rotation for the newly added object

What units is this parameter specified with? It does not seem to be in degrees or radian.

When I try with my example code here where I use `rotation=(0, 1, 0)` to get 1 degree on the y axis. I end up getting `57.296` degrees after running the code.

``````import bpy

bpy.ops.object.lamp_add(type='AREA', view_align=False, location=(0, 0, 0), rotation=(0, 1, 0), layers=(True, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False, False))

It is using radians. `1` radian = `57.2957795` degrees. Without the need to import another module you can use a degree value with `(3.14159 * degrees / 180)` or just quickly import `pi` from `math` if you don't want to define it or you could alternatively use `round(math.radians(degrees))`.
``````import bpy
I recommend to `from math import radians, degrees` for two handy functions to convert back and forth. – CoDEmanX Feb 17 '14 at 0:15
