http://www.builderau.com.au/program/python/soa/Huffman-coding-in-Python/0,2000064084,339283616,00.htm

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.
