How can I assign a new material to an object in the scene via Python?

Here you go, code with some safety checks:
import bpy
ob = bpy.context.active_object
# Get material
mat = bpy.data.materials.get("Material")
if mat is None:
# create material
mat = bpy.data.materials.new(name="Material")
# Assign it to object
if ob.data.materials:
# assign to 1st material slot
ob.data.materials[0] = mat
else:
# no slots
ob.data.materials.append(mat)

$\begingroup$ Thanks for your answer. Is it also possible to specifiy which material (glossy, glass, diffuse) and also the different properties (r,g,b, shinyness)? $\endgroup$ – binaryBigInt Jan 19 '15 at 13:13

1$\begingroup$ Yes, it is also possible to manipulate the material nodes with python, but that is for another question $\endgroup$ – Jaroslav Jerryno Novotny Jan 19 '15 at 13:15

1$\begingroup$ Amazing. These sanity checks actually helped me understand how the things work a lot! $\endgroup$ – Sibbs Gambling Nov 17 '16 at 19:17

"Is it also possible to specify which material (glossy, glass, diffuse)" I don't think this is "another question" because if you do the code above you are working with the principled BSDF added by default but after several researches I found an answer working in blender 2.8 there Add Nodes to Material with Python. you have to work with nodes or you don't really see on what you are working.
