11.5 <tt class="module">ftplib</tt> --
FTP protocol client</A>
</H1>
<P>
<P>
This module defines the class <tt class="class">FTP</tt> and a few related items.
The <tt class="class">FTP</tt> class implements the client side of the FTP
protocol. You can use this to write Python
programs that perform a variety of automated FTP jobs, such as
mirroring other ftp servers. It is also used by the module
<tt class='module'><a href="module-urllib.html" tppabs="http://www.python.org/doc/current/lib/module-urllib.html">urllib</a></tt> to handle URLs that use FTP. For more information
on FTP (File Transfer Protocol), see Internet <a class="rfc" name="rfcref-46994"
href="javascript:if(confirm('http://www.ietf.org/rfc/rfc0959.txt \n\nThis file was not retrieved by Teleport Pro, because it is addressed on a domain or path outside the boundaries set for its Starting Address. \n\nDo you want to open it from the server?'))window.location='http://www.ietf.org/rfc/rfc0959.txt'" tppabs="http://www.ietf.org/rfc/rfc0959.txt">RFC 959 <img src="offsite.gif" tppabs="http://www.python.org/doc/current/icons/offsite.gif"

<P>
Here's a sample session using the <tt class="module">ftplib</tt> module:
<P>
<dl><dd><pre class="verbatim">
>>> from ftplib import FTP
>>> ftp = FTP('ftp.cwi.nl') # connect to host, default port
>>> ftp.login() # user anonymous, passwd user@hostname
>>> ftp.retrlines('LIST') # list directory contents
total 24418
drwxrwsr-x 5 ftp-usr pdmaint 1536 Mar 20 09:48 .
dr-xr-srwt 105 ftp-usr pdmaint 1536 Mar 21 14:32 ..
-rw-r--r-- 1 ftp-usr pdmaint 5305 Mar 20 09:48 INDEX
.
.
.
>>> ftp.retrbinary('RETR README', open('README', 'wb').write)
'226 Transfer complete.'
>>> ftp.quit()
</pre></dl>
<P>
The module defines the following items:
<P>
<dl><dt><b><a name='l2h-2033'><tt class='class'>FTP</tt></a></b> (<big>[</big><var>host</var><big>[</big><var>, user</var><big>[</big><var>,
passwd</var><big>[</big><var>, acct</var><big>]</big><big>]</big><big>]</big><big>]</big>)
<dd>
Return a new instance of the <tt class="class">FTP</tt> class. When
<var>host</var> is given, the method call <code>connect(<var>host</var>)</code> is
made. When <var>user</var> is given, additionally the method call
<code>login(<var>user</var>, <var>passwd</var>, <var>acct</var>)</code> is made (where
<var>passwd</var> and <var>acct</var> default to the empty string when not given).
</dl>
<P>
<dl><dt><b><a name='l2h-2034'><tt>all_errors</tt></a></b>
<dd>
The set of all exceptions (as a tuple) that methods of <tt class="class">FTP</tt>
instances may raise as a result of problems with the FTP connection
(as opposed to programming errors made by the caller). This set
includes the four exceptions listed below as well as
<tt class="exception">socket.error</tt> and <tt class="exception">IOError</tt>.
</dl>
<P>
<dl><dt><b><a name='l2h-2035'><tt class='exception'>error_reply</tt></a></b>
<dd>
Exception raised when an unexpected reply is received from the server.
</dl>
<P>
<dl><dt><b><a name='l2h-2036'><tt class='exception'>error_temp</tt></a></b>
<dd>
Exception raised when an error code in the range 400-499 is received.
</dl>
<P>
<dl><dt><b><a name='l2h-2037'><tt class='exception'>error_perm</tt></a></b>
<dd>
Exception raised when an error code in the range 500-599 is received.
</dl>
<P>
<dl><dt><b><a name='l2h-2038'><tt class='exception'>error_proto</tt></a></b>
<dd>
Exception raised when a reply is received from the server that does
not begin with a digit in the range 1-5.
</dl>

<span class="file">.netrc</span> is typically used by FTP clients to
load user authentication information before prompting
the user.
