Question

I’m working on a simple tool that transfers files to a hard-coded location with the password also hard-coded. I’m a python novice, but thanks to ftplib, it was easy:

import ftplib  info= ('someuser', 'password')    #hard-coded  def putfile(file, site, dir, user=(), verbose=True):     '''     upload a file by ftp to a site/directory     login hard-coded, binary transfer     '''     if verbose: print 'Uploading', file     local = open(file, 'rb')         remote = ftplib.FTP(site)        remote.login(*user)              remote.cwd(dir)     remote.storbinary('STOR ' + file, local, 1024)     remote.quit()     local.close()     if verbose: print 'Upload done.'  if __name__ == '__main__':     site = 'somewhere.com'            #hard-coded     dir = './uploads/'                #hard-coded     import sys, getpass     putfile(sys.argv[1], site, dir, user=info) 

The problem is that I can’t find any library that supports sFTP. What’s the normal way to do something like this securely?

Edit: Thanks to the answers here, I’ve gotten it working with Paramiko and this was the syntax.

import paramiko  host = 'THEHOST.com'                    #hard-coded port = 22 transport = paramiko.Transport((host, port))  password = 'THEPASSWORD'                #hard-coded username = 'THEUSERNAME'                #hard-coded transport.connect(username = username, password = password)  sftp = paramiko.SFTPClient.from_transport(transport)  import sys path = './THETARGETDIRECTORY/' + sys.argv[1]    #hard-coded localpath = sys.argv[1] sftp.put(localpath, path)  sftp.close() transport.close() print 'Upload done.' 

Thanks again!

Paramiko supports SFTP. I’ve used it, and I’ve used Twisted. Both have their place, but you might find it easier to start with Paramiko.
