huffman algorithm in python

Question

HI!

Could anybody say how to fix the problem in the Huffman algorthm (if put together all the parts) from this Internet site:

Error:

 itemqueue =  [Node(a, len(list(b))) for a, b in groupby(sorted(input))]
TypeError: 'builtin_function_or_method' object is not iterable

Thanks!

I think you forgot to declare input. It should work fine otherwise.
