플랫폼 독립적인 SFTP 지원을 제공하는 Python 라이브러리는 무엇입니까?

<code class="python">import paramiko

host = "THEHOST.com"
port = 22
transport = paramiko.Transport((host, port))

password = "THEPASSWORD"
username = "THEUSERNAME"
transport.connect(username=username, password=password)

sftp = paramiko.SFTPClient.from_transport(transport)

import sys
path = './THETARGETDIRECTORY/' + sys.argv[1]
localpath = sys.argv[1]
sftp.put(localpath, path)

sftp.close()
transport.close()
print('Upload done.')</code>

<code class="python">from twisted.conch.ssh import userauth, connection, channel, sftp

password = "THEPASSWORD"
username = "THEUSERNAME"
transport = connection.SSHClientFactory().buildProtocol('localhost', None)
transport.requestService(userauth.SSHUserAuthClientPassword(username, password))

sftp = channel.SSHChannel(transport)
sftp.request_sftp()

import sys
path = './THETARGETDIRECTORY/' + sys.argv[1]
localpath = sys.argv[1]
sftp.sendFile(localpath, path)

sftp.close()
transport.loseConnection()
print('Upload done.')</code>
