X-Replace-Address: [EMAIL PROTECTED] receding_xxxs_.com This wasn't what I was expecting, so I thought I'd ask those more knowledgeable, which is pretty much everybody. Same result on Python 2.3.5 and Python 2.5.1 installed from python.org binaries on Windows XP.
>>> try: set >>> except NameError: from sets import Set as set >>> class myset_fails(set): pass >>> class myset_works(set): >>> def __getitem__(self): pass >>> s = set() >>> fails = myset_fails() >>> works = myset_works() >>> import operator >>> operator.isSequenceType(s) #Not what I expected False >>> operator.isSequenceType(fails) #Not what I expected either False >>> operator.isSequenceType(works) #A hint at what isSequenceType does ? True Are sets not sequences ? I didn't think the isSequenceDisclaimer gave false negatives. See Raymond Hettinger's post here too: http://groups.google.co.uk/group/comp.lang.python/tree/browse_frm/thread /bd04db20cc1f23bb/36f1f48bb7be1e4b?hl=en&rnum=1&q=set+isSequenceType&_do ne=%2Fgroup%2Fcomp.lang.python%2Fbrowse_frm%2Fthread%2Fbd04db20cc1f23bb% 2F0454f5debc01c20d%3Fhl%3Den%26lnk%3Dgst%26q%3Dset%2BisSequenceType%26#d oc_0454f5debc01c20d Although there are suggestions that it means simply that you're headed in the wrong direction design wise: http://www.mail-archive.com/[EMAIL PROTECTED]/msg11576.html but then why have isSequenceType at all ? Not particularly vital. Just implementing __str__ on some class and if one of the members was a sequence I was going to format that bit of data in brackets.
