"One of the reasons that I like to use PyMel is that when you create an
object you get a reference to that object and you are not dependent of the
name when you want to find the object."
Yes, I agree. Well, in this case, you are dependent on the name. Or you
cause a bug. :)
Also I couldn't resist writing this as list comprehensions. Doing it this
way stores your locators as a list of objects that you can reference even
after your range(10) is complete.
locators = [pm.spaceLocator(n='test#') for x in range(10)]
groups = [pm.group(loc, n='group#') for loc in locators]
By the way, zfill() is a nice way to give number padding when making a
numbered naming convention. This would make test_000, test_001, test_002,
etc. ...But this will still cause a nodeError if you don't have unique
names:
locators = [pm.spaceLocator(n='test_{0}'.format(str(x).zfill(3))) for x in
range(10)]
groups = [pm.group(loc, n='group#') for loc in locators]
