Question

我正在运行代码以下载数据并将其保存在本地驱动器中。但是，我得到上面提到的错误信息。请注意，最初我将日期转换为其他格式，并且在保存日期时收到此错误消息。

您能帮我解决这个错误吗？

打印（数据丢失）

谢谢，阿比（Abhay Dodiya）

Answer 1

两个for循环的索引均为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

因此，即使退出第二个循环之后，i中的最后一个值仍然存在。重命名该循环中的计数变量，您的问题就不存在了。在您的情况下，您的日期可能多于股票，因此您会看到错误消息。
