CodePudding user response：

If understand the question correctly, you are trying to rename one column in the dataframe, you can do it as follows:

df.rename(columns={"Close": "Poste_close"}, inplace=True)

CodePudding user response：

If I understand, if your dataframe have only one column

You can do this:

dataset_poste.columns = ['Poste_close']

And if you have other columns to rename:

dataset_poste.columns = ['Poste_close', 'Adj Close', 'Volume']

Remember: Always in dataframe column order
