 Some languages are very strict about purity and don't even have assignment
 statements such as ``a=3`` or ``c = a + b``, but it's difficult to avoid all

 Python programs written in functional style usually won't go to the extreme of
 avoiding all I/O or all assignments; instead, they'll provide a
