元组和列表可以互相转化

1、tuple----------->list()：

  >>> t         (1, '23', [123, 'abc'], ('python', 'learn'))>>> tls = list(t)                           #tuple-->list>>> tls[1, '23', [123, 'abc'], ('python', 'learn')]2、list------------->tuple():>>> t_tuple = tuple(tls)                    #list-->tuple>>> t_tuple(1, '23', [123, 'abc'], ('python', 'learn'))
