Question

我在尝试将数据导出为.csv格式时遇到此错误。

我尝试以管理员身份运行该应用程序，但它无效。

请帮助新手！

以下是代码：

import pandas as pd
tickers = ['AAPL', 'MSFT', 'XOM', 'BP']
portfolio_selection = pd.DataFrame()
for t in tickers:
     portfolio_selection = wb.DataReader(tickers, 'google', start = '2005-1-1')['Close']
portfolio_selection
portfolio_selection.to_csv('C:\Users\PC\Documents\Lucas\Random_Folder')

这就是我所拥有的

 IOError: [Errno 13] Permission denied: 'C:\Users\PC\Documents\Lucas\Random_Folder'

我不确定这个错误在Windows上会是什么样子但是我想它是因为你需要一个文件名。（在Mac上，您的代码会抛出IsADirectoryError: [Errno 21] Is a directory: Random_Folder）

这样的事情应该解决它：

portfolio_selection.to_csv('C:\Users\PC\Documents\Lucas\Random_Folder\portfolio_selection.csv')

IOError：[Errno 13]权限被拒绝：导出到.csv
