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

You can use pandas.DataFrame.filter method to either filter or reorder columns like this:

df1 = df.filter(['a', 'b'])

This is also very useful when you are chaining methods.
