Hi Vkash,
If I understand correctly, you do seem to be a bit confused. May I ask
what you are trying to achieve?
Django is a web framework meaning that it's using the HTTP protocol
which is itself an application layer protocol. SFTP is another
application layer protocol so you cannot really implement that in Django.
There is at least one implementation of SFTP in Python though:
https://www.paramiko.org/
But of course, that has absolutely nothing to do with Django.
So again, maybe start out by telling us what you really want to achieve?
Kind regards,
Kasper Laudrup
