Greetings! I have the following function: def _convert_auto(self, value): if value.args or value.kwds or value.value is _auto_null: ... if source_len < target_len : prev_values = [] ... gnv = self._generate_next_value if self._auto_args: ... values = gnv(key, self._start, len(self._member_names), prev_values, *values) else: values = gnv(key, self._start, len(self._member_names), prev_values) ... return value Towards the bottom there are two calls that both start with values = gnv(key, self._start, ... The variable `key` does not exist -- is PyFlakes supposed to catch that? -- ~Ethan~
