Ahh, my pitiful form of flattening a list that cheats...
def flatten(li):
    li = str(li)
    li = li.replace("[","")
    li = li.replace("]","")
    li = li.replace("(","")
    li = li.replace(")","")
    li = "[%s]"%li
    return eval(li)
It works! It's probably just a bit slower.

Actually, this doesn't even work 100% of the time. If you have a list as 
the key or value in a dictionary, it will remove the brackets, at which 
point eval will fail since the dictionary will look like

{7:8,9,10} (assuming an original dictionary of {7:[8,9,10]}), which 
results in a SyntaxError
