Index error - columns vs non-column

[Vinny]

Dear users,

I am getting an IndexError, and not sure why? The code (below) works perfectly when I run it using data.cvs. On that type of file, the index is a column (named Date).

But, if I run the code directly from an input library (e.i., df = yf.download(tickers=ticker, start=start, end=end), I receive the trackback message's below. In this example, the date is not considered a column. So, I think the error comes from that; however, I don't know how to fix it.

I hope I am being clear. It is my first post, and I am a beginner.

Thank you

This is my Code:

df_close_adj = pd.DataFrame(data=df[["Close", "Adj_Close"]].to_numpy(), index=df["Date"], columns=[["Close", "Adj_Close"]])

The Traceback I get is this:

Error:
---------------------------------------------------------------------------

   2899             except KeyError as err:

KeyError: 'Date'

The above exception was the direct cause of the following exception:
