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