[issue12005] modulo result of Decimal differs from float/int
New submission from Daniel Albeseder ko...@gmx.at:
I know that the modulo operation for negative values is not well defined, but I
would at least expect that the result is the same no matter if you use ints,
floats or decimals. However Decimal seem to behave else than the builtin types.
Python 3.1.2 (release31-maint, Sep 17 2010, 20:27:33)
[GCC 4.4.5] on linux2
Type help, copyright, credits or license for more information.
from decimal import Decimal
-3 % 5
2
-3. % 5.
2.0
Decimal(-3) % Decimal (5)
Decimal('-3')
I could reproduce the same for python 2.6.6.

[issue9182] document “--” as a way to disti nguish option w/ narg='+' from positional argument in arg parse
Daniel Albeseder ko...@gmx.at added the comment: Steven: From msg121850 I think the last two examples do not need the --. Since there are no positional arguments, the -- is not needed. However the following additional cases exist: -x X [X ...] -y Y -- A B # since optionals might come in other order Basically every of the three variable length classes need to be tested: ZeroOrOne, ZeroOrMore and OneOrMore. This might always come in a conflict with positional arguments needed afterward (even with optional positional arguments!). BTW - I recognized the following seem to be supported: for [-x [X ...]] -- [y ...] the following input: a -x -- b I would expect to be 'a' and 'b' positional arguments and the optional '-x' has no argument. However this seem not to work. Another issue or desired behavior? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9182 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Daniel Albeseder ko...@gmx.at added the comment: Steven: The last part I guess would belong better in issue 9334. Using a -- to end all optionals is just a convention but -- could also be the argument to some option as well. We need to limit this in any way, and the way it is done right now seem very reasonable for me. Adding some additional unit tests testing this limits might be beneficial but I guess would be best done during issue 9334. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9182 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10453] Add -h/--help option to compileall
Daniel Albeseder ko...@gmx.at added the comment: I wanted to test, that no unwanted output is given before the usage. I just added the test before I started to try to fix this bug, as I recognized Michele already was already fixing the bug. This was just my test-driven approach, where the unit test failed before the fix, and should pass afterwards. As the unwanted output was the main reason for the issue, I just did put this into the test. However I agree that the test at all is silly, and I fully agree if it is not used. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10453 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
