                         THE WHILE STATEMENT

                  The while statement executes a set of statements repeatedly, till 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:

                  while (test expression):
                      Statements
                      Increment/Decrement

                       The While Loop Using Else Statement
                  Python enables the use of else statement with the while loop. The else block is executed when the
                  condition given in the while statement becomes false.
