You have a bug in line 40 of pysftp.py. You should change that to:

print ("passwd")

Also, you might want to show people how to use raw_input to get the password rather than hardcode.

So change it to

passwd = raw_input('Type in your password:')

Thanks for the script. However, I am getting

Are you sure you want to continue connecting (yes/no)? string when logging into sftp server the first time. After that I use p.interact(), so that user can type yes/no. But I want to send the password like you have sent (from the script), not the user entering it. Can you pls. help how can I switch back to my script after, taking yes/no from user.
