Making Maya’s Python palatable

Maya’s python interface leaves something to be desired, as it seems like a straight port of their existing MEL interface with no additional thought put into designing a nice OO interface. For example, here is how to set or get the ‘radius’ attribute of a sphere:

s = cmds.sphere()
r = cmds.sphere(s, query=True, radius=True)
cmds.sphere(s, edit=True, radius=10)

Nasty.

So, here is a wrapper to make things nicer:

import maya.cmds as cmds
 
class Wrapper(object):
	def __init__(self, other):
		self.__dict__['me'] = other()
 
	def __getattr__(self, thing):
		i = 0 if cmds.attributeQuery(thing, node=self.__dict__['me'][0], exists=True) else 1
		return cmds.getAttr(self.__dict__['me'][i] + "." + thing)
 
	def __setattr__(self, thing, value):
		i = 0 if cmds.attributeQuery(thing, node=self.__dict__['me'][0], exists=True) else 1
		cmds.setAttr(self.__dict__['me'][i] + "." + name, value)

The above example is now:

s = Wrapper(cmds.sphere)
r = s.radius
s.radius = 10
