How to translate this small MEL script into Python?

[kaleido]

Hi everyone,

I've been looking online for a couple of hours on how to translate a Mel script into Python, but I still can't seem to get the idea processed into my head. 
How do I convert this into Python? Thanks.

//objs:
string $objA = "pSphere1";
string $objB = "pCube1";
//store all objB verts:
string $objBV[] = ls -fl ($objB+".vtx[0:]");
//run loop on each one to gather their world positions and place a duplicate of objA at that position:
for($v in $objBV){
float $pos[] = xform -q -a -ws -t $v;
string $dup[] = duplicate $objA;
xform -a -ws -t $pos[0] $pos[1] $pos[2] $dup;
}

import maya.cmds as mc

#objs:
objA = "pSphere1"
objB = "pCube1"

#store all objB verts:
objBV = mc.ls(objB+".vtx[0:]", flatten=True)

#run loop on each one to gather their world positions and place a duplicate of objA at that position
for v in objBV:
    pos = mc.xform(v, q=True, a=True, ws=True, t=True)
    dup = mc.duplicate(objA)
    mc.xform(dup, a=True, ws=True, t=(pos[0], pos[1], pos[2]))
