Check if single element is contained in Numpy Array

Question

I just want to check if a numpy array contains a single number quickly similar to contains for a list. Is there a concise way to do this?

a = np.array(9,2,7,0)
a.contains(0)  == true

Answer 1

You can use 0 in a. i.e

a = np.array([9,2,7,0])
0 in a
