Hello, I'm a python-list newbie. I've got a question about doctest; perhaps a bug report.
I really like doctest, but sometimes doctest gives a failure when the output looks absolutely fine to me -- indeed, even after I have gone to considerable effort to make my documentation match the output perfectly. http://www.aims.ac.za/~mackay/python/compression/huffman/Huffman3.py The above file is an example. It's self-contained, so you can plop it into emacs and hit C-cC-c to run the doctests. One of them fails. The piece of source code concerned is here: >>> c = []; \ c.append(node(0.5,1,'a')); \ c.append(node(0.25,2,'b')); \ c.append(node(0.125,3,'c')); \ c.append(node(0.125,4,'d')); \ iterate(c) ; reportcode(c) # doctest: +NORMALIZE_WHITESPACE, +ELLIPSIS #Symbol Count Codeword a (0.5) 1 b (0.25) 01 c (0.12) 000 d (0.12) 001 """ And the output is: Failed example: c = []; c.append(node(0.5,1,'a')); c.append(node(0.25,2,'b')); c.append(node(0.125,3,'c')); c.append(node(0.125,4,'d')); iterate(c) ; reportcode(c) # doctest: +NORMALIZE_WHITESPACE, +ELLIPSIS Expected: #Symbol Count Codeword a (0.5) 1 b (0.25) 01 c (0.12) 000 d (0.12) 001 Got: <__main__.internalnode instance at 0xb7aee76c> #Symbol Count Codeword a (0.5) 1 b (0.25) 01 c (0.12) 000 d (0.12) 001 =================================== I have tried numerous tweaks, and am at a loss. I am wondering whether there is some big in doctest involving the "#" character in the output. Or maybe I made some silly mistake. Any advice appreciated! Many thanks again to the authors of doctest, it gives a great feeling to write code in the way that doctest encourages. :-) David -- David J.C.
