2、原子分组(Atomic group) 使用语法:(?>regex)这里的?和>都是语法的组成部分;原子分组是贪婪的匹配,当文本和这个分组匹配的成功后,正则表达式引擎在匹配后面的表达式时不会发生回溯行为及尽可能多的匹配,注意这个分组的贪婪行为和++这种贪婪匹配略有不同,++只能对正则表达式字符进行多次贪婪匹配如(bc|b)是没办法...

For example, if the pattern is(?P<id>[a-zA-Z_]\w*), the group can be referenced by its name in arguments to methods of match objects, such asm.group('id')orm.end('id'), and also by name in the regular expression itself (using(?P=id)) and replacement text given to.sub()(...
