Question

I've finished problem 10 in ps_5 and passed all the tests in the test harness, but when I run ps_5.py it doesn't return stories it just keeps looping printing "Polling"..."Sleeping"...
I'm using WinXP and IDLE

Answer 1

Could you dpaste or pastebin your code, I'll take a look at it.

Answer 3

@osdsb I added (import pprint) at the top in the imports section so I could print out the stories object and see how it changed as it went through main()

Then, commented out everything in the main function and started uncommenting a line at a time from the top, pprinting stories each time it changed:

# Get stories from Google's Top Stories RSS news feed
stories = process(" http://news.google.com/?output=rss ")
pprint.pprint(stories)

# Get stories from Yahoo's Top Stories RSS news feed
stories.extend(process(" http://rss.news.yahoo.com/rss/topstories "))
pprint.pprint(stories)

# Only select stories we're interested in
stories = filter_stories(stories, triggerlist)
pprint.pprint(stories)

What I found is that after you run filter_stories, stories ends up empty ... everything gets filtered out of it, that's why you're not getting any output there.

Your issue is in Part 3 Filtering

Near the end of:
def filter_stories(stories, triggerlist):

If I comment out these two lines in the stories loop, it starts working:
for story in stories:
## for trig in triggerlist:
## if trig.evaluate(story):
filteredStories.append(story)
return filteredStories

Answer 4

hmm...interesting. You're right. But if I take those lines out then the test harness fails. http://dpaste.com/787422/

I'm stuck in my own real life programming loop!

Thanks for the help, I'll see what I can do.

Answer 5

ok, i think my code is correct and working properly. None of the trigger words actually appear in the fields searched so all the entries were filtered out. I changed the search terms and it gave me results.

Awesome :)
