there is no standard support in python for SFTP.
paramiko is a python library that supports SFTP.
when I looked at it, use did non seem too hard.
you could use the option to use might want to use the 'user
communication scripts'-option.
paramiko is a python solution. There are more solution, eg using
OpenSSH, putty, cURL.
all of these could be used by a user communication script.
in fact, that is why I made it possible to have user scriptable
communication.
advantage of eg OpenSSH is that it is a very 'proven' solution with good
documentation.
(btw, there is SFTP and FTPS, which is confusing)
