I just gave this a try and got:

Looks like I need to add Python 2.5+Linux to my testing set. I did not
expect that the UNIX distributions of Python 2.5 would ship with
wintypes.py at all. I think I can fix this on the spot though. On line
40, you'll find this bit:
except ImportError:
Change that to the following:
except ImportError,ValueError:
And it should pass that point. If it doesn't, you can try the completely
general:
except:
And then it should be OK. I should probably use that formulation in that
particular section.
(This is also my #1 beef with Python: too many utterly impenetrable
error messages... or at least impenetrable to me.)
That one made sense to me, but that is one of the sharper parts of its
learning curve. I think part of the problem is that much of the tutorial
Python code out there never gets into error handling. One of the things
Java does that I miss is that if you create a "try" block, it won't work
until you have addressed every possible exception the code in there can
generate. It may be impractical for Python to know that much, but I
wonder if a lint-ish tool for the language might be able to do it.
The above mumbling is certainly off-topic for this list though.
