regarding printing out the floating number with correct digit values

I have two variables, np.sum(train_y) and train_x.shape[0]. When printing them separately, they are:

print('np.sum(train_y) ',np.sum(train_y))
print('train_x.shape[0] ',train_x.shape[0])

('np.sum(train_y) ', 398)
('train_x.shape[0] ', 213605)

However, their computed ratio is printed out as 0 instead of 0.00186.

print('np.sum(train_y)/train_x.shape[0]  ',np.sum(train_y)/train_x.shape[0])


('np.sum(train_y)/train_x.shape[0]  ', 0)

How can I get the value computed correctly?

`np.sum(train_y)/float(train_x.shape[0])` py2 uses floor division – Chris_Rands Feb 03 '18 at 18:47
