IndexError：单个位置索引器在下载数据时出现越界错误

Question

我正在运行代码来下载数据并将它们保存在本地驱动器中。但是，我收到上述错误消息。请注意，最初我已将日期转换为不同的格式，在保存它们时我收到此错误消息。

你能帮我解决这个错误吗？

进口quandl 导入操作系统 将熊猫导入为 pd 将日期时间导入为 dt 导入全局

如果 name == "ma​​in":

打印（data_missing）

谢谢， 阿拜·多迪亚

两个for循环的索引都是i。这会导致潜在的意外行为：

for i in range(2):
     for i in range(3,11):
         pass
     print(i)

给予

10
10

所以即使在退出第二个循环之后，i 的最后一个值仍然存在。重命名该循环中的计数变量，您的问题应该消失了。 在您的情况下，您的日期可能比股票多，因此请注意您的错误消息。
