Spotted while reviewing Cython's proposed implementation of the pattern matching syntax (https://github.com/cython/cython/pull/4897#discussion_r1489177169) where there was a bug my the reimplementation that wasn't caught against the CPython tests here. files: M Lib/test/test_patma.py diff --git a/Lib/test/test_patma.py b/Lib/test/test_patma.py index 298e78ccee3875..1bdab125dc6ef0 100644 --- a/Lib/test/test_patma.py +++ b/Lib/test/test_patma.py @@ -2957,6 +2957,14 @@ def test_invalid_syntax_3(self): pass """) + def test_len1_tuple_sequence_pattern_comma(self): + # correct syntax would be `case(*x,):` + self.assert_syntax_error(""" + match ...: + case (*x): + pass + """) + def test_mapping_pattern_keys_may_only_match_literals_and_attribute_lookups(self): self.assert_syntax_error(""" match ...: _______________________________________________ Python-checkins mailing list -- [email protected] To unsubscribe send an email to [email protected] https://mail.python.org/mailman3/lists/python-checkins.python.org/ Member address: [email protected]
