This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

some python function is not working in maya?

hi, i am new to python ... recently i had watched some tutorial about python. and i try it, it work in IDLE but when i apply in MAYA it doesn't work... am i doing wrong?

the sample given in tutorial :
s = [1, 2, 3, 4, 5]
a, *b, c = s
2, 3, 4

and here what i tried in maya2018:
import maya.cmds as cmds
selObj = #(i did select few item in maya)
a,*b = selObj
print (a)

and i get # Error: invalid syntax #

thanks in advance for spending timeuser added image

Asterisk (*) unpacking is introduced in python 3 , Maya still uses python 2 so this method won't work
Instead you can use this code:
import maya.cmds as cmds
selObj =
a,b = selObj[0],selObj[1:]
print a
print b

Its because in Python 3, print statement has been replaced with a print() function, with keyword arguments to replace most of the special syntax of the old print statement. But if you write this in a program and someone using Python 2.x tries to run it, they will get an error. To avoid this, it is a good practice to import print function:

from __future__ import print_function

Now your code works on both python2 and python3
