No, the best thing to do would be to change:
    if type(data) is list:
to:
    if isinstance(data, list):

Since the code is suboptimal but not incorrect, it is not imperative that it be changed, which is why I suggested simply adding a #TODO comment. I'm not sure why adding a comment about a better way to write the code counts as "touching" the code; that's what I thought the whole point of #TODOs were.
