New submission from Terry J. Reedy <[EMAIL PROTECTED]>: Python 3.0a3 (r30a3:61161, Mar 1 2008, 22:51:17) [MSC v.1500 32 bit (Intel)] on win32
>>> a,b=1,1//1 >>> a is b False IDLE 3.0a3 >>> a,b=1,1//1 >>> a is b True ditto for 2.5.2 interpreter On c.l.p, Duncan Booth wrote I've had a look to see why this happens: long division (and in Python 3 all integers are longs) allocates a new long to hold the result of the division so it will never use one of the preallocated 'small int' values. That maybe explains the change from 2.5 but not the difference from IDLE. More important, the small int checks are present with the other operations: >>> 1*1 is 1 True >>> 1+1 is 2 True >>> 1-1 is 0 True >>> 1**1 is 1 True so the omission with // is plausibly a bug. ---------- components: Interpreter Core messages: 64037 nosy: tjreedy severity: normal status: open title: Integer floor division (//): small int check omitted type: behavior versions: Python 3.0 __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue2417> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
