Category: Python Interpreter Core Group: Python 2.4 >Status: Closed >Resolution: Invalid Priority: 5 Submitted By: Simon Dahlbacka (sdahlbac) Assigned to: Nobody/Anonymous (nobody) Summary: list comprehension scope Initial Comment: The variable used for iteration in list comprehensions is still in scope after the list comprehension. >>>foo = [1, 2, 3] >>>bar = [dummy + 1 for dummy in foo] >>>dummy 3 Expected result: NameError: name 'dummy' is not defined ---------------------------------------------------------------------- >Comment By: Raymond Hettinger (rhettinger) Date: 2005-01-27 08:48 Message: Logged In: YES user_id=80475 This is not a bug. It is behaving as designed. The thought was to emulate the behavior of an equivalent for-loop. In future versions of Python, Guido would like to change the design to hide the induction variable. So, someday, you'll get your wish. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1110705&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
