Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Core (C code) Group: Python 2.6 Status: Open Resolution: None Priority: 5 Private: No Submitted By: Anthony Baxter (anthonybaxter) >Assigned to: Nobody/Anonymous (nobody) Summary: from __future__ import print_function Initial Comment: This was done partly as a learning exercise, partly just as a vague idea that might prove to be practical (chatting with Neal at the time, but all blame is with me, not him!) The following adds 'from __future__ import print_function' to 2.x. When this is enabled, 'print' is no longer a statement. Combined with copying bltinmodule.c:builtin_print() from the p3yk trunk, this should give some compatibility options for 2.6 <-> 3.0 Note that for some reason I don't fully understand, this doesn't work in interactive mode. For some reason, in interactive mode, the parser flags get reset for each line. Wah. ---------------------------------------------------------------------- >Comment By: Guido van Rossum (gvanrossum) Date: 2007-01-17 10:24 Message: Logged In: YES user_id=6380 Originator: NO I don't think we need to do anything special for exec, as the exec(s, locals, globals) syntax is already (still :-) supported in 2.x with identical semantics as in 3.0. except E as V *syntax* can go in without a future stmt; and (only when that syntax is used) it should also enforce the new semantics (V must be a simple name and is deleted at the end of the except clause). I think Anthony's patch is a great idea, but I'll refrain from reviewing it. I'd say "just do it". :-) ---------------------------------------------------------------------- Comment By: Neal Norwitz (nnorwitz) Date: 2007-01-17 02:42 Message: Logged In: YES user_id=33168 Originator: NO Guido, this is the patch I was talking about wrt supporting a print function in 2.6. exec could get similar treatment. You mentioned in mail that things like except E as V: can go in without a future stmt. I agree. ---------------------------------------------------------------------- Comment By: Anthony Baxter (anthonybaxter) Date: 2007-01-12 02:31 Message: Logged In: YES user_id=29957 Originator: YES Updated version of patch - fixes interactive mode, adds builtins.print File Added: print_function.patch ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=305470&aid=1633807&group_id=5470 _______________________________________________ Patches mailing list Patches@python.org http://mail.python.org/mailman/listinfo/patches
