As a tip for future reference (e.g. in case someone googles this),
I've had good success using Python's built in set() objects for
handling this problem. They're fast and memory efficient. So my code
goes something like:
seenCategories = set();
# then in my loop:
if not cat.title() in seenCategories:
seenCategories.add(cat.title());
# do something with this category
Cheers,
Morten
