[Tutor] Unlimited string

Strings (like "Hello") are limited by the amount of memory in your
machine.  I'm going to assume that you aren't talking about strings in
the Python datatype sense.

Yes.  Using generators, you can construct infinite sequences.  An
example:

  >>> def positive_integers():
  ...     x = 1
  ...     while True:
  ...         yield x
  ...         x += 1
  ... 
  >>> i = positive_integers()
  >>> i.next()
  1
  >>> i.next()
  2
  >>> i.next()
  3

Peace,
