I have this dataframe

pd.DataFrame([[-1,1,2,3,4],[-2,5,6,7,8]],columns[["col_other","cola","colb","colc","cold"]])

enter image description here

given the table above how do I create a column col_combine that is a list of previous four columns i.e., the values of two rows of col_combine are [1,2,3,4] and [5,6,7,8] respectively.
