New submission from Weihong Guan: According to the doc:
For the '?' format character, the return value is either True or False. When packing, the truth value of the argument object is used. Either 0 or 1 in the native or standard bool representation will be packed, and any non-zero value will be True when unpacking. But it behaves more like & 1 operation. so False for even value, and True for odd value. unpack fmt '?H' should reqiure buff of length 3, same as 'H?', not 4. ---------- components: ctypes files: Screen Shot 2016-10-06 at 20.59.43.png messages: 278192 nosy: Weihong Guan priority: normal severity: normal status: open title: struct.unpack of Bool type: behavior versions: Python 2.7 Added file: http://bugs.python.org/file44987/Screen Shot 2016-10-06 at 20.59.43.png _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28377> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
