Python 3.9 and 3.10 are concerned by this issue: integer singletons are per-interpreter since Python 3.9. Should Python 3.9 and 3.10 be fixed? "x is 0" is recommended and should be used. For example, the compiler emits a SyntaxWarning: $ python3.9 >>> x=0 >>> x is 0 <stdin>:1: SyntaxWarning: "is" with a literal. Did you mean "=="? True I propose to only fix the main branch and so close the issue. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45691> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
