	"""
	The master class for all sets objects.

	Positional arguments:
		No arguments required.

		format : str ................... The format to return. Defaults to JSON.
		pretty : bool ... Makes the returned JSON prettier. The library may not work properly with this setting.

	Attributes:
		object : str ...... Returns the type of object it is. (card, error, etc)
		code : str ........................ The three letter set code of the set
		mtgo_code : str ........................ The mtgo equivalent of `code()`
		name : str ................................... The full name of the set.
		set_type : str ......... The type of the set (expansion, commander, etc)
		released_at : str ....................... The date the set was launched.
		block_code : str ..... The the letter code for the block the set was in.
		block : str ................... The full name of the block a set was in.
		parent_set_code : str ................. The set code for the parent set.
		card_count : int ......................  The number of cards in the set.
		digital : bool .............. True if this set is only featured on MTGO.
		foil : bool ........................... True if this set only has foils.
		icon_svg_uri : str ................  A URI to the SVG of the set symbol.
		search_uri : str .................. The scryfall API url for the search.
