You can also use a combination of columns as the index for the dataframe, in that case, pass the list of columns as the argument. You can also pass inplace=True to modify the dataframe in place, in which case, the set_index() function changes the original dataframe and does not return any value.

It returns the updated dataframe (with the column set as the index). # set combination of columns as dataframe's index
