Maya Python - Create object & Randomize Translate

from maya import cmds
import random

numObjects = 4

for n in range(numObjects):
    obj = cmds.polyCube()
    cmds.setAttr(obj[0]+'.translateX', random.randint(0, 5))
    cmds.setAttr(obj[0]+'.translateY', random.randint(0, 5))
    cmds.setAttr(obj[0]+'.translateZ', random.randint(0, 5))

Maya Python - Randomize translate of selection #1

from maya import cmds
import random

objList = cmds.ls(selection=True)

print objList

for obj in objList:
    cmds.setAttr(obj+'.translateX', random.randint(0, 5))
    cmds.setAttr(obj+'.translateY', random.randint(0, 5))
    cmds.setAttr(obj+'.translateZ', random.randint(0, 5))

Maya Python - Randomize translate of selection #2

#La meme chose en utilisant une fonction
from maya import cmds
import random

objList = cmds.ls(selection=True)

print objList

#On definit la fonction
def randomize(minValue=0, maxValue=5):
    for obj in objList:
        cmds.setAttr(obj+'.translateX', random.randint(minValue, maxValue))
        cmds.setAttr(obj+'.translateY', random.randint(minValue, maxValue))
        cmds.setAttr(obj+'.translateZ', random.randint(minValue, maxValue))

#On change si besoin les valeurs par defaut avant d'executer la fonction
randomize(minValue=4, maxValue=20)
