Entered the values ​​of the array a = asarray (input ()). How now to turn to any element?

you entered one line

 In [337]: a = np.asarray(input()) 1 2 3 4 In [338]: a Out[338]: array('1 2 3 4', dtype='<U7')

if you need to break it into numbers:

 In [341]: a = np.array(input().split()).astype(int) 1 2 3 4 In [342]: a Out[342]: array([1, 2, 3, 4]) In [343]: a.dtype Out[343]: dtype('int32')

How to multiply all the elements of an array?

 In [336]: a.prod() Out[336]: 24
