@adam-grant-hendry those are all refactor types, this means that these will be marked as hints. These won’t show red/yellow squiggles. If you want you can change their severity by setting this:

"pylint.severity": {
    "convention": "Information",
    "error": "Error",
    "fatal": "Error",
    "refactor": "Warning", // <--- By default this is Hint.
    "warning": "Warning",
    "info": "Information"
}

@karthiknadig Thank you, that was the issue. For reference (future readers), with the python.linting.pylint extension, the same arguments are:

  // Severity of Pylint message type 'Convention/C'.
  "python.linting.pylintCategorySeverity.convention": "Information",

  // Severity of Pylint message type 'Error/E'.
  "python.linting.pylintCategorySeverity.error": "Error",

  // Severity of Pylint message type 'Fatal/F'.
  "python.linting.pylintCategorySeverity.fatal": "Error",

  // Severity of Pylint message type 'Refactor/R'.
  "python.linting.pylintCategorySeverity.refactor": "Hint",  // <--- By default this is Hint.

  // Severity of Pylint message type 'Warning/W'.
  "python.linting.pylintCategorySeverity.warning": "Warning",
