Aaron, In this case you might want to consider using a dictionary. Instead of a list of tuples, you would get: {'http://www.news.com/frontdoor/0-1.html?tag=hd_ts': 'CNET', 'http://www.news.com/shopping/0-1257.html?tag=hd_ts': 'Price comparisons'} This would allow you to access each dictionary entry using the URL as the key: elem = pAnchors['http://www.news.com/frontdoor/0-1.html?tag=hd_ts'] # would yield 'CNET' If you desired, you could also have the dictionary value for each key be a tuple.

I am writing a script which returns a list of tuples, like so:

[('http://www.news.com/frontdoor/0-1.html?tag=hd_ts', 'CNET'), ('http://www.news.com/shopping/0-1257.html?tag=hd_ts', 'Price comparisons')]

My question (and it's a dumb one) is: how do I refer to the individual values within the tuples when iterating through the list?

Here's what I've got so far:

myCount = 0

for elem in p.anchors: for elem in elem: print myCount, ": ", elem[0:] myCount = myCount + 1

count=0 for tuple in list_of_tuples: print count, tuple[1], ":", tuple[0] # Alternative print statement print "%s %s: %s" % (count,tuple[1],tuple[0]) count=count+1 The syntax elem[0:] picks out all member from 0 to the end of the list or tuple. Also, it is asking for trouble to use the same variable name ("elem") in the inner and outer loops. Cheers, Tom P
