THE WHILE STATEMENT


                 The while statement executes a set of statements repeatedly, until the logical expression evaluates
                 to true. When the condition becomes false, the control comes out of the loop. The syntax of while
                 statement is given below.
                 Syntax:
                                                                                                               False
                 while <test expression>:                                                      Test Expression
                        Statements

                        increment/decrement statement                                                  True
                                                                                             Execute while Block

                     Any non-zero value in the while loop indicates always a true condition, whereas zero indicates
                                                        always-false condition.
