To create a connection, call the class using these argument: host, user, passwd, acct These are all strings, and have default value ''. Then use self.connect() with optional host and port argument. To download a file, use ftp.retrlines('RETR ' + filename), or ftp.retrbinary() with slightly different arguments. To upload a file, use ftp.storlines() or ftp.storbinary(), which have an open file as argument (see their definitions below for details). The download/upload functions first issue appropriate TYPE and PORT or PASV commands. isicsIjk|o8l|i|m|om|i|||nndS(N(shostsselfsconnectsusersloginspasswdsacct(sselfshostsuserspasswdsacct((s/usr/lib/python2.2/ftplib.pys__init__js  c s|ors|os||_nt|ot||_nud}vxti|i|idtiDv]}w|\}}}}} xy2yti||||_ z|i i| WnN{tij o<}||i o}|i in~t|_ qhnXPqhW|i oti|n||_|i id|_|i|_|iSdS(sConnect to host.
