Create a DataFrame from another DataFrame by column

Question

I would like to create a data frame from another data frame - but I want to do it by specifying the coordinates. In this case I want the new DataFrame to contain only the first column.

The following is correct in that it works:

US_effective_rate = US_forward_rates.iloc[:,1].copy()
US_effective_rate = US_effective_rate.to_frame()

I was wondering if there's a better implementation, possibly using .filter()?

there are similar questions but they reference column names, not coordinates.

thank you very much.

PS: I actually just want the dimensions and index from the first frame, going to overwrite the actual data. Any chance I could do THAT in one hit?

Answer 1

是的，您只需添加[]

US_forward_rates.iloc[:,[1]]
