Creating list from retrlines in Python
<p>How exactly would you create a list of the entries in an FTP directory?</p>

<p>This is my code so far:</p>

<pre><code>import ftplib

files = []

my_ftp = ftplib.FTP(HOST)
my_ftp.login(USERNAME,PASSWORD)

line = my_ftp.retrlines("NLST",files.append(line))
my_ftp.quit()
</code></pre>

<p>The error says that the variable line is being used before it is defined.</p>
