  Explaining how Python integers work (they don't overflow), we came
  up with an overflow demo in C.

* :doc:`/trainings/material/soup/python/basics/python_0220_for/topic`

  * ``while`` and ``for`` in C (similar in Jave and C#): ``for`` is
    just a shorthand for ``while`` - as opposed to Python.

  * Solution 1: relatively explicit and long

  * Solution 2: dense, short, requires a bit of programming pratice
    (not much though)
