How to get mesh vertex position through Maya API

Sometime back, I was in need of getting the vertex position, through Maya API.Then I have written the one, which suits my requirement. Here is the code:

#_ Get Api MDagPath for object
activList =MSelectionList()
activList.add(vtxObj)
pathDg =MDagPath()
activList.getDagPath(0, pathDg)

#_ Iterate over all the mesh vertices and get position of required vtx
mItVtx =MItMeshVertex(pathDg)
vtxPos=[]
while not mItVtx.isDone():
if mItVtx.index() == vtxNum:
point =MPoint()
point =mItVtx.position(MSpace.kWorld)
vtxPos =[round(point.x, 5), round(point.y, 5), round(point.z, 5)]
break
mItVtx.next()

#_ Print or return your vtx position
print [vtxPos]

#For Example
getMeshVtxPos('pSphere1.vtx[60]')
