while

Overview

The while statement allows the conditional iteration of a local code block.

Syntax

variable_declaration = while condition
    …
    continue
    …
    break
    …
    return_expression

Remarks

• The local code block after the initial while line must be indented with four spaces or a tab. For the while loop to terminate, the boolean expression following while must eventually become false, or a break must be executed.
