why not do like everyone else, and put your instances
in a list?

    persons = []
    for i in range(some_random_integer):
        persons.append(People())

    print person[0]

or even

    persons = [People() for i in range(some_random_integer)]

it can be done, but as usual, Python works better if you use it
to write Python code.
