How to handle IncompleteRead: in python

I am trying to fetch some data from a website. However it returns me incomplete read. The data I am trying to get is a huge set of nested links. I did some research online and found that this might be due to a server error (A chunked transfer encoding finishing before reaching the expected size). I also found a workaround for above on this link

However, I am not sure as to how to use this for my case. Following is the code I am working on

br = mechanize.Browser()
br.addheaders = [('User-agent', 'Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1;Trident/5.0)')]
urls = "http://shop.o2.co.uk/mobile_phones/Pay_Monthly/smartphone/all_brands"
page = urllib2.urlopen(urls).read()
soup = BeautifulSoup(page)
links = soup.findAll('img',url=True)

for tag in links:
    name = tag['alt']
    tag['url'] = urlparse.urljoin(urls, tag['url'])
    r = br.open(tag['url'])
    page_child = br.response().read()
    soup_child = BeautifulSoup(page_child)
    contracts = [tag_c['value']for tag_c in soup_child.findAll('input', {"name": "tariff-duration"})]
    data_usage = [tag_c['value']for tag_c in soup_child.findAll('input', {"name": "allowance"})]
    print contracts
    print data_usage

Please help me with this.Thanks

The link you included in your question is simply a wrapper that executes urllib's read() function, which catches any incomplete read exceptions for you. If you don't want to implement this entire patch, you could always just throw in a try/catch loop where you read your links. For example:

try:
    page = urllib2.urlopen(urls).read()
except httplib.IncompleteRead, e:
    page = e.partial

for python3

try:
    page = request.urlopen(urls).read()
except (http.client.IncompleteRead) as e:
    page = e.partial
