"""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).
