New submission from Christoph Zwerschke <[EMAIL PROTECTED]>:
When you sort a list with list.sort() or sorted(list), and set the
reverse parameter to None, then you get the following misleading error
message:
TypeError: an integer is required
I would expect a more proper error messa
Christoph Zwerschke <[EMAIL PROTECTED]> added the comment:
The problem is not only that the error message "TypeError: an integer is
required" has "integer" instead of "boolean", but it does not mention
the attribute name "reverse", i.e. it does n
Christoph Zwerschke <[EMAIL PROTECTED]> added the comment:
The unspecific error message is thrown by the vgetargskeywords()
function, so changing this behavior would be a larger, more difficult
and general issue (similar to #1283289). We could go another path and
require an object for &#
Christoph Zwerschke <[EMAIL PROTECTED]> added the comment:
Agree. Seems to be a more general weakness of the argument parsing of
builtin functions and methods, that calls for a general solution instead
of a local patch. Luckily there are not so many cases where the errors
are misleading,
Christoph Zwerschke <[EMAIL PROTECTED]> added the comment:
Small improvement of the patch: Instead of hardcoding the BOM as
'\xef\xbb\xbf', we should use codecs.BOM_UTF8.

The following code throws a NameError which seems to be a bug existing
since Python 2.4 up to the current 2.5.2.

Christoph Zwerschke added the comment:
Thanks for the quick explanation. I understand that class scopes don't
extend and this is documented behavior.
However, the question is why the if clause is executed in a scope of its
own and where this is documented.
You would expect that the proble
Christoph Zwerschke added the comment:
Thanks, this now makes sense to me. You're right, it's rather an ugly
wart than a bug.
But I think the Python reference needs to be improved to make this clear
enough.
How about the following proposed addtions (in square brackets) to
section 5

My point was that it's not immediately obvious what "by default" means and that
hashability is not only affected by the __hash__ method but also by __eq__.
But I agree, you can argue that "by default" already includes not ad
