subtract(~) method takes in two array and performs an element-wise subtraction.
Opt for direct subtraction (i.e.
arr_one - arr_two) instead
Unless you need the second and third parameters of the method, opt to directly use
- operator instead for a performance boost.
The first input array.
The second input array.
Numpy array |
Instead of creating a new array, you can place the result into the array specified by
Values that are flagged as False will be ignored, that is, their original value will be uninitialized. If you specified the
out parameter, the behavior is slightly different - the original value will be kept intact.
A scalar is returned if
a is a scalar, otherwise a Numpy array is returned.
a = np.array([1,2,3])b = np.array([6,5,4])np.subtract(a,b)array([-5, -3, -1])
