Selecting multiple columns in a pandas dataframe

Question

I have data in different columns but I don\'t know how to extract it to save it in another variable.

index  a   b   c
1      2   3   4
2      3   4   5


        

Answer 1

To select multiple columns, extract and view them thereafter: df is previously named data frame, than create new data frame df1, and select the columns A to D which you want to extract and view.

df1 = pd.DataFrame(data_frame, columns=['Column A', 'Column B', 'Column C', 'Column D'])
df1

All required columns will show up!
