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 -side effects. Printing to the screen or writing to a disk file are side -effects, for example. For example, in Python a call to the :func:`print` or -:func:`time.sleep` function both return no useful value; they're only called for -their side effects of sending some text to the screen or pausing execution for a -second. +side effects, such as printing to the screen or writing to a disk file.

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
