程序中的Python代码错误应该计算出Google的月平均价格，并告诉我们Google的最佳和最差的6个月期间

Question

我需要帮助来找出如何修复Python代码分配中的错误。 基本上，我需要创建一个程序，应该计算谷歌的月平均价格，告诉我们最好和最差的六个月期间谷歌。 平均价格定义为（（v1*c1）+（v2*c2）+（v3*c3）+（v4*c4）…+（vn*cn））/（v1+v2+v3+v4…+vn），其中vi是第一天的成交量，ci是第一天的调整收盘价。 对于这项任务，我们将从2004年到2012年考察谷歌。我们需要的数据集是一个CSV格式的表，可以从https://www.dropbox.com/s/qr7cu2kui654kgz/googlePrices.csv下载。在

到目前为止，我已经创建了下面的Python代码，但是它显示了一些错误消息，我无法理解。在

提前谢谢你。在

谨致问候， 罗伯托·莱尔
