Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. >Category: Documentation Group: None Status: Open Resolution: None Priority: 5 Submitted By: Master_Jaf (master_jaf) Assigned to: Nobody/Anonymous (nobody) Summary: class property fset not working Initial Comment: Classes which are not instantiated from 'object', containing properties, are not working as expected. The GET method is working but not the SET method. Tested with python 2.4.1 und 2.3.5. See sample code file. ---------------------------------------------------------------------- >Comment By: Terry J. Reedy (tjreedy) Date: 2005-05-26 12:37 Message: Logged In: YES user_id=593130 For people who learned Python with old-style classes, it is 'obvious' that properties are a new addition that came with and work with new-style classes. Can you suggest specific places in the docs where clarification could be made? Or should be close this? (I suspect that setting is more complicated than getting but would not have expected even the get method to work.) ---------------------------------------------------------------------- Comment By: Master_Jaf (master_jaf) Date: 2005-05-24 08:27 Message: Logged In: YES user_id=1140154 After reading some more documentation I've found at Python Tutorial "D. Glossary" more hints. <cite> Any class that inherits from object. This includes all built-in types like list and dict. Only new-style classes can use Python's newer, versatile features like __slots__, descriptors, properties, __getattribute__(), class methods, and static methods. </cite> Fine. OK, understood.. I'm tending to agree with mwh's opinion, that this is a documentation bug, although I don't fully understand why the GET descriptor is working but unlikly not the SET descriptor. ---------------------------------------------------------------------- Comment By: Michael Hudson (mwh) Date: 2005-05-24 03:58 Message: Logged In: YES user_id=6656 At the very limit, this is a documentation bug. Why did you think properties could be attached to old-style classes? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1207379&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
