How to change the weights of a deformer from a script in Maya?

How to change the weights of a deformer from a script in Maya?

This question is ideally for Pymel in Maya 2013, but if it is not possible I would still be interested to know the answer in Python, MEL, or using the C++ Maya-API.

for deformers, you can query weight in python as :

VertexNb = cmds.polyEvaluate(Mesh, v=1) - 1
weight = cmds.getAttr('{0}.weightList[0].weights[0:{1}]'.format(deformerNode, VertexNb))

for blendshape :

VertexNb = cmds.polyEvaluate(Mesh, v=1)
weight = cmds.getAttr('{0}.inputTarget[0].baseWeights[0:{1}]'.format(blendShapeNode, VertexNb))

To set value :

cmds.setAttr('{0}.weightList[0].weights[0:{1}]'.format(deformerNode, VertexNb), *weight, size=len(weight))
