Let us now see some examples of the use of the for statement that includes an else part.
        Example:
          01 for i in range(1,4):
          02     print('i=', i)
          03     print('i*i=', i*i)
          04 else:
          05     print('End of forloop\'s body')
          06     print('Else part may also include several statements')
        Sample Output:

              i=1
              i*i = 1
              i=2
              i*i=4
              i=3
              i*i=9
              End of forloop's body
              Else part may also include several statements
        Note that the statements in the else-block are executed after all iterations of the loop.
        Example:
          01 for i in range(4,1):
          02     print('i=', i)
          03     print('i*i=', i*i)
          04 else:
          05     print('End of forloop\'s body')
          06     print('Else part may also include several statements')
        Sample Output:

              End of forloop's body
              Else part may also include several statements
        Note that as range(4,1) yields an empty sequence, beginning with 4, we cannot count up to 1. So, no iterations of the
        loop's body are executed. However, the statements in the else block are still executed.



          C T  02     What will be the output produced on the execution of the following program segment?

                      for i in range(-4):
                          print('i=', i)
                          print('i*i=', i*i)
                      else:
                          print('Hello')


        Example:
         >>> for i in range(6):
         ...     print(i, end=' ')
         ...     i = 10
         ...     print(i)
         ...
         ...
              0 10
              1 10
              2 10
              3 10
