Python - Efficiently capturing a string with a specific number?

Question

Python

From a large number of html pages of the same type, you need to pick up only one line with the same number, say, eleventh. How can this be done most efficiently, faster than:

<font color="black"><a href="http://s-c.me/15443/s">Copy Source</a> | <a href="http://s-c.me/15443/h">Copy HTML</a><br/>
<font color="#0000ff">for</font> i, line <font color="#0000ff">in</font> <b>enumerate</b>(page):<br/>
    <font color="#0000ff">if</font> i == <font color="#008000">10</font>:<br/>
        s = line + <font color="#008000">'\n'</font><br/>
        outfile.write(s)<br/>
    <font color="#0000ff">elif</font> i &gt; <font color="#008000">10</font>:<br/>
        <font color="#0000ff">break</font><br/>
 <br/>
</font>

Answer 1

There is another way, I don’t know how much faster, but shorter for sure:

Answer 2

If page is not a list, then convert to this type

outfile.write('%s\n' % list(page)[10])

Answer 3

page.splitlines()[10]

Answer 4

Why read the entire page when you can only read the essentials:
>>> import urllib2
>>> p = urllib2.urlopen('http://habrahabr.ru/')
>>> for i in xrange(10):
... p.readline()
>>> print p.readline()
