[python] Run local python script on remote server

Although this question isn't quite new and an answer was already chosen, I would like to share another nice approach.

Using the paramiko library - a pure python implementation of SSH2 - your python script can connect to a remote host via SSH, copy itself (!) to that host and then execute that copy on the remote host. Stdin, stdout and stderr of the remote process will be available on your local running script. So this solution is pretty much independent of an IDE.

On my local machine, I run the script with a cmd-line parameter 'deploy', which triggers the remote execution. Without such a parameter, the actual code intended for the remote host is run.

import sys
import os

def main():
    print os.name

if __name__ == '__main__':
    try:
        if sys.argv[1] == 'deploy':
            import paramiko

            # Connect to remote host
            client = paramiko.SSHClient()
            client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
            client.connect('remote_hostname_or_IP', username='john', password='secret')

            # Setup sftp connection and transmit this script
            sftp = client.open_sftp()
            sftp.put(__file__, '/tmp/myscript.py')
            sftp.close()

            # Run the transmitted script remotely without args and show its output.
            # SSHClient.exec_command() returns the tuple (stdin,stdout,stderr)
            stdout = client.exec_command('python /tmp/myscript.py')[1]
            for line in stdout:
                # Process each line in the remote output
                print line

            client.close()
            sys.exit(0)
    except IndexError:
        pass

    # No cmd-line args provided, run script normally
    main()

Exception handling is left out to simplify this example. In projects with multiple script files you will probably have to put all those files (and other dependencies) on the remote host.
