Handling division by zero in Pandas calculations

Question

I have the following data:

a = pd.Series([1, 2, 3])
b = pd.Series([0, 0, 0])

If there is a division by zero I want to in some cases

Answer 1

You can also use the np.isinf function to check for infinite values and then substitue them with 0. Ex-

a = np.asarray(np.arange(5))
b = np.asarray([1,2,0,1,0])

c = a/b
c[np.isinf(c)] = 0

#result
>>> c
array([ 0. ,  0.5,  0. ,  3. ,  0. ])
