Something like this?
def item_attrs (feed_url, attr):
"""Return a list of the item titles found in this feed url"""
data = []
feed = feedparser.parse(feed_url)
if feed:
if len(feed.version) > 0:
for e in feed.entries:
data.append(getattr(e, attr).encode('utf-8'))
return data
You're not making it clear how the data.append... line changes so it's
hard to know exactly.
