Interpreting basic Python program
<p>I'm reading a book on basic python and need help translating this program.
It will be my first program, so don't laugh at me please.</p>

<p>I need a step by step guide with this; when I click print and it says <code>fname not found</code>.</p>

<hr>

<pre><code>#!/usr/bin/env python

# 'makeTextFile.py -- create text file'

import os
ls = os.linesep

# get fileneame
while True:

    if os.path.exists(fname):
        print "ERROR: '%s' already exists" % fname
    else:
        break

# get file content (text) lines
all = []
print "\nEnter lines (' . ' by itself to quit). \n"

# loop until user terminates input
while True:
    entry = raw_input('&gt; ')
    if entry == '.':
        break
    else:
        all.append(entry)

# write lines to file with proper line-ending
fobj = open(fname, 'w') 
fobj.writelines(['%s%s' % (x, ls) for x in all])
fobj.close()
print 'DONE'
</code></pre>
