I am trying to run the following screen scraping script but it's not displaying any output. Can someone tell me what I'm doing wrong?

python Syntax (Toggle Plain Text) 
  1. from BeautifulSoup import BeautifulSoup
  2. import urllib
  3.  
  4. url = 'http://toronto.en.craigslist.ca/search/cta?query=civic&minAsk=min&maxAsk=max'
  5.  
  6. doc = urllib.urlopen(url).read()
  7. soup = BeautifulSoup(doc)
  8. tags = soup.findAll('p')
  9. for tag in tags:
  10.     addate = tag.contents[0]
  11.     path = tag.contents[1].attrs[0][1]
  12.     desc = tag.next.next.string
  13.     print addate, path, desc

How are you running the code? If you're just double clicking the .py file perhaps the console is closing before you're able to capture the output...

1. Use Code Tags.
2. Homework? Show Effort.
3. Keep discussions on the forum: no PMs

My bad. I was running the code from idle and kept getting a 'RuntimeError: maximum recursion depth exceeded' error message. I am not quite sure why but it works from the console. Thanks!
