how to multiply pandas dataframe with numpy array with broadcasting

I find an alternative way to do the multiplication between pandas dataframe and numpy array.

In [14]: x.multiply(y, axis=0)
Out[14]: 
          0         1         2
0  0.195346  0.443061  1.219465
1  0.194664  0.242829  0.180010
2  0.803349  0.091412  0.098843
3  0.365711 -0.388115  0.018941

I think you are better off using the df.apply() method. In your case:

x.apply(lambda x: x * y)
