Pylint output

************* Module unittestprog1
unittestprog1.py:16:16: C0209: Formatting a regular string which could be a f-string (consider-using-f-string)

Expected behavior

Do not flag a modulo (%) operation on a string with the consider-using-f-string lint.

(I discovered this issue while working on converting the justbytes module [ https://github.com/mulkieran/justbytes ] to formatted strings:)

class ModTestCase(unittest.TestCase):
    """Test mod."""

    def test_exceptions(self):
        """Test that exceptions are thrown."""

Apologies; the description is supposed to be a reproducer program that can be executed via python3 -m unittest -v unittestprog1.py after saving the output to a file named "unittestprog1.py".
