Sorry praveen, we don’t edit code using Photoshop. Please don’t post screenshots or photos of code.

In future, please ask your questions using words, and copy and paste your code, and the full error message starting with the line “Traceback” to the end, into your post using a code fence (three backticks):

But my guess is that you are using Python version 2.7, is that right?

Version 2.7 is old and obsolete and no longer supported, you really should use version 3.10 if you can, or if not then at least version 3.6.

But in version 2.7 you should use raw_input instead of input.

unable to use a screenshot. And we cannot copy/paste from a screen shot.

Please just post your code directly into your message, along with a
complete error traceback showing your problem, between backticks like
