How to convert output to list to count it amount?

I wrote a script that parses a webpage and get the amount of links('a' tag) on it:

import urllib
import lxml.html
connection = urllib.urlopen('http://test.com')
dom =  lxml.html.fromstring(connection.read())
for link in dom.xpath('//a/@href'):
    print link

The output of a script:

./01.html
./52.html
./801.html
http://www.blablabla.com/1.html
#top

How can i convert it to list to count the amount of links? I use link.split() but it got to me:

['./01.html']
['./52.html']
['./801.html']
['http://www.blablabla.com/1.html']
['#top']

But i want to get:

[./01.html, ./52.html, ./801.html, http://www.blablabla.com/1.html, #top]

Thanks!

list(dom.xpath('//a/@href'))

This will take the iterator that dom.xpath returns and puts every item into a list.

link.split() tries to split link itself. But you must work with entity that represents all links. In your case: dom.xpath('//a/@href').

So this must help you:

links = list(dom.xpath('//a/@href'))

And getting length with a built-in len function:

print len(links)
