How can I repeat the command in for loop?

Question

I'm trying to perform duplicate a sphere in z axis 10 times and then duplicate this whole copied spheres X and Y axis.

And I'm stuck after first step like this. Can I get some advice how I can repeat this duplication to X and Y?

import maya.cmds as cmds

cmds.polySphere(r=0.5, sx=10, sy=10)
for i in range(0, 9):
    cmds.duplicate()
    cmds.move(0, 0, 2, r=True)

If you're trying to make a cube of spheres, you just need 3 loops for each axis. To get the spacing right you multiply whatever the sphere's radius by 2:

import maya.cmds as cmds

count = 4
radius = 0.5

for x in range(count):  # Loop in x axis.
    for y in range(count):  # Loop in y axis.
        for z in range(count):  # Loop in z axis.
            # Create a new sphere.
            transform, psphere = cmds.polySphere(r=radius, sx=10, sy=10)

            # Move it.
            cmds.move(
                x * radius * 2, 
                y * radius * 2,  
                z * radius * 2, 
                transform)

This will result like this:
