The TagFile function takes a filepath as a parameter and returns the class which corresponds to its container. If an unsupported filetype is passed in, the UnsupportedFileType error is raised. Each class presents the same metadata interface, which have the following attributes:

title: str
version: str
album: str
artist_album: List[str]
catalog_number: str
release_type: str
comment: str
date.year: int
date.date: str
track_number: str
track_total: str
disc_number: str
disc_total: str
genre: List[str]
label: str
artist = {
  ArtistRoles.MAIN: List[str]
  ArtistRoles.FEATURE: List[str]
  ArtistRoles.REMIXER: List[str]
  ArtistRoles.PRODUCER: List[str]
  ArtistRoles.COMPOSER: List[str]
  ArtistRoles.CONDUCTOR: List[str]
  ArtistRoles.DJMIXER: List[str]
}
image_mime: str
image: bytes

Fields can be edited by setting new values to the attributes of the TagFile. To edit the date, which is special, assign a string in the format of %Y-%m-%d or %Y to the date attribute. To save the changes made to the tags, call the save() method.
