I've got a data frame df1 with multiple columns and rows. Simple example:

    TIME T1  T2 

       1 10 100

       2 20 200

       3 30 300

I'd like to create an empty data frame df2 and later on, add new columns with the calculation results.

For this moment my code looks like this:


     df2=df1.copy()[[]] #copy df1 and erase all columns

...adding two new columns:


Is there any better/safer/faster way to do this ? Is it possible to create an empty data frame df2 and only copy index from df1 ?

The below code creates the data frame with no columns only the index number the same as the df1.

df2 = pd.DataFrame(index=df1.index)
