To create a connection, call the class using these arguments: host, user, passwd, acct, timeout The first four arguments are all strings, and have default value ''. timeout must be numeric and defaults to None if not passed, meaning that no timeout will be set on any ftp socket(s) If a timeout is passed, then this is now the default timeout for all ftp socket operations for this instance. 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. rNr zlatin-1FcCs0||_||_|r,|||r,||||dSN)source_addresstimeoutconnectlogin)selfhostuserpasswdacctrrrrr__init__rs  z FTP.__init__cCs|Srrrrrr __enter__{sz FTP.__enter__c GsN|jdk rJz*z |Wnttfk r0YnXW5|jdk rH|XdSr)sockclosequitOSErrorEOFError)rargsrrr__exit__s    z FTP.__exit__cCs|dkr||_|dkr||_|dkr*||_|dk r8||_td||j|jtj|j|jf|j|jd|_|jj |_ |jj d|j d|_ ||_|jS) awConnect to host.
