New submission from Ned Batchelder <n...@nedbatchelder.com>:
(Using CPython commit 6b1ac809b9) This program never executes line 6, but tracing it claims that it does: a = b = x = y = z = 1 if a == 1: if b == 1: x = 4 else: y = 6 else: z = 8 assert (a, b, x, y, z) == (1, 1, 4, 1, 1) Using a simple trace program (https://github.com/nedbat/coveragepy/blob/master/lab/run_trace.py), it produces this output: call <string> 1 @-1 line <string> 1 @0 line <string> 2 @20 line <string> 3 @28 line <string> 4 @36 line <string> 6 @40 line <string> 9 @52 return <string> 9 @76 ---------- components: Interpreter Core messages: 384222 nosy: Mark.Shannon, nedbat priority: normal severity: normal status: open title: Nested if/else gets phantom else trace (3.10) versions: Python 3.10 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42810> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
