Category: Python Interpreter Core Group: Python 2.5 >Status: Closed >Resolution: Fixed Priority: 9 Submitted By: Anthony Tuininga (atuining) >Assigned to: Neal Norwitz (nnorwitz) Summary: unpack list of singleton tuples not unpacking Initial Comment: The following code works differently in Python 2.5 than Python 2.4: x = [(1,), (2,), (3,)] for y, in x: print y In Python 2.4, this code produces the following: 1 2 3 In Python 2.5, this code produces the following: (1,) (2,) (3,) Interestingly enough the following code: x = (1,) y, = x print y produces the output 1 in both Python 2.4 and Python 2.5. I'm thinking this is not intentional. :-) ---------------------------------------------------------------------- >Comment By: Neal Norwitz (nnorwitz) Date: 2006-07-11 22:26 Message: Logged In: YES user_id=33168 Awww come on, can't we change the language just to make your life difficult? ;-) Thanks a lot for catching this!

This is bad. The disassembly shows that the compiler isn't generating the unpack_sequence opcode. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1520864&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
