>>> a = ("aaa","bbb","ccc","ddd","eee") >>> type(a) <class 'tuple'>
>>> a[:2] + ("xxx",) + a[2:] ('aaa', 'bbb', 'xxx', 'ccc', 'ddd', 'eee') >>> a[:3] + ("xxx","yyy") + a[3:] ('aaa', 'bbb', 'ccc', 'xxx', 'yyy', 'ddd', 'eee') >>> a * 2 ('aaa', 'bbb', 'ccc', 'ddd', 'eee', 'aaa', 'bbb', 'ccc', 'ddd', 'eee') >>> b = ("xxx","yyy") >>> type(b) <class 'tuple'>
>>> a + b ('aaa', 'bbb', 'ccc', 'ddd', 'eee', 'xxx', 'yyy') >>> b + a ('xxx', 'yyy', 'aaa', 'bbb', 'ccc', 'ddd', 'eee')
