`corpus_bleu` function does not catch all the expections when calling `weights[0][0]` about nltk HOT 3 CLOSED

Hello!

The function's parameter is supposed to be a tuple.

It can also be a list of tuples, as explained in the docstring. I suspect that the author of this piece of code lived by the EAFP principle for Python, causing this code to not be so strange at all. Beyond that, NLTK lives by a garbage-in-garbage-out rule, so incorrectly typed inputs can't be expected to work.
That all said, I'll resolve your issue by replacing except TypeError with just except, but in the future I would watch your writing tone with these bug reports.
