Python script for connecting an emitter to a curve

Connect an emtiter to a curve

Select an emitter and a curve and run this script:

       
       
## PYTHON            
def attachEmitterToCurve():

    emitter = maya.cmds.ls(sl=True, type="pointEmitter")
    if len(emitter) != 1:
        print("You must select one emitter and one nurbs curve")
        return False
    nodes = maya.cmds.ls(sl=True, type = "transform")
    nurbsCurves = {}
    
    for x in nodes:

        if len(kids) == 0:
            continue
        nurbsCurves[x] = kids
