Subtract a Series from a DataFrame while keeping the DataFrame struct intact

Question

How can I subtract a Series from a DataFrame, while keeping the DataFrame struct intact?

df = pd.DataFrame(np.zeros((5,3)))
s = pd.Series(np.ones(5))

df - s         


        

Answer 1

Maybe:

>>> df = pd.DataFrame(np.zeros((5,3)))
>>> s = pd.Series(np.ones(5))
>>> df.sub(s,axis=0)
   0  1  2
0 -1 -1 -1
1 -1 -1 -1
2 -1 -1 -1
3 -1 -1 -1
4 -1 -1 -1

or, for a more interesting example:

>>> s = pd.Series(np.arange(5))
>>> df.sub(s,axis=0)
   0  1  2
0  0  0  0
1 -1 -1 -1
2 -2 -2 -2
3 -3 -3 -3
4 -4 -4 -4
