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.

S ) aw Connect to host. Arguments are:
- host: hostname to connect to (string, default previous host)
- port: port to connect to (integer, default previous port)
- timeout: the timeout to set against the ftp socket(s)
- source_address: a 2-tuple (host, port) for the socket to bind
to as its source address before connecting.

If the transfer is active, send a port command and the
transfer command, and accept the connection. If the server is
passive, send a pasv command, connect to it, and start the
transfer command. Either way, return the socket for the
connection and the expected size of the transfer. The
expected size may be None if it could not be determined.
Optional `rest' argument can be a string that is sent as the
argument to a REST command. This is essentially a server
marker used to tell the server to skip over any data up to the
given marker.

dddZdd ZdS )FTP_TLSa A FTP subclass which adds TLS support to FTP as described
in RFC-4217.
Connect as usual to port 21 implicitly securing the FTP control
connection before authenticating.
Securing the data connection requires user to explicitly ask
for it by calling prot_p() method.
Usage example:
>>> from ftplib import FTP_TLS
>>> ftps = FTP_TLS('ftp.python.org')
>>> ftps.login() # login anonymously previously securing control channel
'230 Guest login ok, access restrictions apply.'
>>> ftps.prot_p() # switch to secure data connection
'200 Protection level set to P'
>>> ftps.retrlines('LIST') # list directory content securely
