I had seen the examples during google search, still I hoped for an
answer to my exact situation. I know for sure there will be no
renaming and creating like the above objects = [MyClass() for i in
range(100)].
as for the z = MyClass(some, args, 'z') I had it in my mind but I
hoped to have something automatic, w/o the arg 'z'.
