Unicode类别数据库
unicategories的Python项目详细描述
单一类别
Unicode类别数据库，在安装时生成。
此模块公开包含RangeGroup实例的类别字典。
示例
fromunicategoriesimportcategoriesupperchars=categories['Lu'].characters()# iteratorprint('Unicode uppercase caracters are "%s"'%''.join(upperchars))# Unicode uppercase caracters are "ABCDEF..."
范围组
不可变iterable（基于元组，使用一些有用的方法）的（开始，结束）
元组就像python的range，在末尾打开。
为了提高存储效率，我们选择了这种方法，分别存储 记忆中的字符会占用大量的记忆。
rangegroup类提供以下方法：
range_group.characters()
Get iterator with all characters on this range group. :yields:iterator of characters (str of size 1):ytype:str
range_group.codes()
Get iterator for all unicode code points contained in this range group. :yields:iterator of character index (int):ytype:int
range_group.has(character)
Get if character (or character code point) is contained by any range on this range group. :param character:character or unicode code point to look for:type character:str or int:returns:True if character is contained by any range, False otherwise:rtype:bool
