if len(tags) == 0

Couldn't you just say something like:
if tags is None:
    # 'Error' handling
elif not tags: 
    # Empty list case
else:
    # Process returned list
I like it better than saying "if len(tags) == 0", and if you've already tested for None then it has the same effect. What do you think?
