python - Pandas two dataframes multiplication? -
i have 2 data frames (a , b)
a: column 1, column 2, column 3 0.1 0.5 0.7 b: row 1 5 row 2 6 row 3 7
how perform multiplication like
(0.1)*5, (0.5)* 6, , (0.7)*7?
in other words, how multiply value in first row of b value in first column of a, second row of b value in second column of b, , etc?
you want multiply values without respect whether rows or columns.
pd.series(a.values.ravel() * b.values.ravel()) 0 0.5 1 3.0 2 4.9 dtype: float64
