i am new to data science .I have been learning about numpy library in python.But i don't know what division operator do on numpy array

import numpy as np;
x=np.array([3.4,4.08]);
y=np.array([1.5,1.8]);
print(x/y);
z=np.sum(x/y);
print(z);

By the way, you don't need to use semicolons in Python – OneCricketeer Dec 23 '19 at 05:35
Like addition and multiplication, it is element-wise, `[3.4/1.5, 4.08/1.8]`. More generally, there are `broadcasting` rules, but here it is a simple pairing of the values. – hpaulj Dec 23 '19 at 05:37
