你这应该是从c啊之类的语言里面学的习惯吧，当你for i in L的时候，它迭代的不是下标1、2、3，它迭代的是里面的元素，在这句里迭代的是[1,2,3]和后面的两个列表。所以你这句话按机器理解的是area*=L[[1,2,3][5,3,2]]，很明显，这是错的。所以这个错误报告给你说list的下标应该是整数或者是划分，不能是个列表。想达到你想要的效果，就for i in range(len(L)吧，但就算是按下标算，你思路也是错的。

有关系！例如： “{0}{2}{1}".format(100,200,300) 输出结果为：100 300 200 “{0}{1}{2}".format(100,200,300) 输出结果为：100 200 300 “{ }{ }{ }".format(100,200,300) 输出结果为：100 200 300 默认顺序输出
