"""WHILE statement
@see: https://docs.python.org/3/tutorial/controlflow.html
@see: https://docs.python.org/3/reference/compound_stmts.html#the-while-statement
The while loop executes as long as the condition remains true. In Python, like in C, any
non-zero integer value is true; zero is false. The condition may also be a string or list
value, in fact any sequence; anything with a non-zero length is true, empty sequences are
false.
The test used in the example is a simple comparison. The standard comparison operators are
written the same as in C: < (less than), > (greater than), == (equal to), <= (less than or
equal to), >= (greater than or equal to) and != (not equal to).
