New submission from Roger Taylor <roger.taylor.em...@gmail.com>:
An IntFlag member before 3.8.6 was converted to an integer in an f-string. After 3.8.6, the textual IntFlag class and member name are placed in the interpolated f-string instead of the integer. 3.8.3: f"... {X.F} ..." where X.F = 1 << 4 will give "... 16 ..." 3.8.5: Same 3.8.6: f"... {X.F} ..." where X.F = 1 << 4 will give "... X.F ..." I have reproduced this on Linux using the version compiled and installed by pyenv, and on Windows using the 32-bit versions from the downloadable standalone installer. Now I have to locate and go through all my SQL statements and verify that they explicitly convert IntFlag values to integer to avoid the errors introduced by this regression. ---------- components: Interpreter Core messages: 377793 nosy: rt121212121 priority: normal severity: normal status: open title: Regression in IntFlag behaviour in f-string type: behavior versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41907> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
