How to duplicate special multiple groups using python in maya

I am having a question for my college assignment, in which I am creating a plane pattern using polygons, and I successfully create one line of the pattern on the x-axis and group the objects in a group, and I duplicate the group one time on the z-axis. While I have two groups now, the part of my code of duplicating the groups looks like this:

cmds.select(all=True)
cmds.group(name='group#')
cmds.select('group1')
cmds.duplicate('group1')
cmds.move(0.9, 0, 1.6)
cmds.select('group1','group2')
cmds.group(name='group#')
cmds.select('group3')
cmds.duplicate('group3')
cmds.move( 0, 0, 3.2 )
cmds.duplicate( st=True )
cmds.duplicate( st=True )
cmds.duplicate( st=True )
cmds.duplicate( st=True )

'''

So how can I simplify this code by using a loop?

Solution

Based on your comment above, if we ignore the grouping you are doing and just focus on looping, you could do something like this to create a cube-grid of poly cubes:

import maya.cmds as cmds

iterations = 10
distanceIncrement = 2

for x in range(iterations-1):
    cube = cmds.polyCube()
    cmds.setAttr('{}.translate'.format(cube[0]), x*distanceIncrement, 0, 0)
    
    for y in range(iterations-1):
        cube = cmds.polyCube()
        cmds.setAttr('{}.translate'.format(cube[0]), x*distanceIncrement, y*distanceIncrement, 0)
        
        for z in range(iterations-1):
            cube = cmds.polyCube()
            cmds.setAttr('{}.translate'.format(cube[0]), x*distanceIncrement, y*distanceIncrement, z*distanceIncrement)

You can use the same technique of nested loops to create a variety of patterns, so hopefully this lets you work towards a solution to your specific problem.
