您如何展平以下元组

埃西尔·金斯

我有以下元组

TOPICS = (
    (_('Politics and Government'), (
            (1,  _('(1) Women politicians, women electoral candidates...')),
            (2,  _('(2) Peace, negotiations, treaties...(local, regional, national),')),
            (3,  _('(3) Other domestic politics/government (local, regional, national), elections, speeches, the political process ...')),

    ),
    (_('Economy'), (

我想将其展平以仅获取内部元组列表

[(1,  _('(1) Women politicians, women electoral candidates...')),
(2,  _('(2) Peace, negotiations, treaties...(local, regional, national),')),
(18, _('(18) Other stories on the economy (specify the topic in \'Comments\' section of coding sheet)'))]
