Hello @Pramod Kumar Velayudhan,

Thank you for contacting us. 

What exactly are you trying to do with the REST-API?

We can help you here to ensure that you've got the right endpoint, but if you're trying to develop something for Jira with Python, you might want to check out the Atlassian Developer Community instead. In that Community, you'll find more folks who are familiar with developing for Atlassian and will be able to help you out.
