Proxies in Python FTP application

Question

I\'m developing an FTP client in Python ftplib. How do I add proxies support to it (most FTP apps I have seen seem to have it)? I\'m especially thinking about SOCKS proxies,

As per this source.

Depends on the proxy, but a common method is to ftp to the proxy, then use the username and password for the destination server.

E.g. for ftp.example.com:

Server address: proxyserver (or open proxyserver from with ftp)
User:           anonymous@ftp.example.com
Password:       password

In Python code:

from ftplib import FTP
site = FTP('my_proxy')
site.set_debuglevel(1)
msg = site.login('anonymous@ftp.example.com', 'password')
site.cwd('/pub')
