Consider the file SarojiniPoem.txt

Q. Consider the file “SarojiniPoem.txt”

 

Autumn Song

 

Like a joy on the heart of a sorrow,

The sunset hangs on a cloud;

A golden storm of glittering sheaves,

Of fair and frail and fluttering leaves,

The wild wind blows in a cloud.

 

Hark to a voice that is calling

To my heart in the voice of the wind:

My heart is weary and sad and alone,

For its dreams like the fluttering leaves have gone,

And why should I stay behind?

 

Sarojini Naidu

for line in text  :

    print (line , end = ' ' )

print ( )

 

(b) Modify the program so that the lines are printed in reverse order.
