I have a simple class ConfigFile declared using the @property annotation to define properties. The properties are defined as follows: @property def sections(self) -> 'list[ConfFileSection]': """This is a list of ConfFileSection objects, containing the names of all the sections of the config.""" if not self.__sectslist_: self.__sectslist_ = [] return self.__sectslist_ @sections.setter def sections(self, action, *args)->None: if not self.__sectslist_: self.__sectslist_ = [] if action == 'update': for a in args: if type(a) == ConfFileSection: self.__sectslist_.append(a) else: raise CfpTypeError() elif action == 'overwrite': self.__sectslist_ = [] for a in args: self.__sectslist_.append(a) elif action == 'empty': self.__sectslist_ = [] elif action == 'refresh': self.__secnames = self.__get_section_names_from_conffile() for name in self.__secnames: pass @property def location_dirpath(self) -> str: return self.__locdirpath @location_dirpath.setter def location_dirpath(self, lp) -> None: self.__locdirpath = lp @property def filename(self) -> str: return self.__file_name @filename.setter def filename(self, fname) -> None: self.__file_name = fname As you can see, it defines three properties. The init method has the following signature: def __init__(self, sections: list=[], location_dirpath: str, filename: str): However, when I try defining the init method, Pylance is underlining the location_dirpath: str portion in red. The reason it gives is: non default argument follows default argument The location_dirpath property is defined using the same annotation as the rest, so why is Pylance not accepting it as an argument?
