I think there have been some improvements merged with https://bugs.python.org/issue12458 . I am not sure if the patch covers more cases. I ran the tests attached in the patch and some of them cause RuntimeError in master. # bpo26452.py def f(): return [j for i in range(3) if i] f() # Master ./python.exe Python 3.8.0a0 (heads/master:c510c6b8b6, Sep 21 2018, 11:10:24) [Clang 7.0.2 (clang-700.1.81)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> ./python.exe ../backups/bpo26452.py Traceback (most recent call last): File "../backups/bpo26452.py", line 6, in <module> f() File "../backups/bpo26452.py", line 2, in f return [j File "../backups/bpo26452.py", line 2, in <listcomp> return [j NameError: name 'j' is not defined # Python 3.7 python3.7 ../backups/bpo26452.py Traceback (most recent call last): File "../backups/bpo26452.py", line 6, in <module> f() File "../backups/bpo26452.py", line 3, in f for i in range(3) File "../backups/bpo26452.py", line 4, in <listcomp> if i] NameError: name 'j' is not defined # Tests ./python.exe ../backups/test26452.py ..F ====================================================================== FAIL: test_operators (__main__.TestPEP380Operation) ---------------------------------------------------------------------- Traceback (most recent call last): File "../backups/test26452.py", line 21, in expect_line f() File "../backups/test26452.py", line 98, in f - RuntimeError During handling of the above exception, another exception occurred: Traceback (most recent call last): File "../backups/test26452.py", line 100, in test_operators self.expect_line(f, 3) # want 2 File "../backups/test26452.py", line 26, in expect_line self.assertEqual(relative_line, expected_relative_line) AssertionError: 2 != 3 ---------------------------------------------------------------------- Ran 3 tests in 0.001s FAILED (failures=1) Thanks ---------- nosy: +xtreak _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue26452> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
