In NumPy, thenumpy.divide()function is used to divide the elements of one array by the elements of another array. It performs element-wise division, broadcasting the arrays if necessary. This function provides several parameters that allow the user to specify what value to divide with. Usenumpy...
array = np.random.randint(20, size=12) array output array([ 0, 1, 8, 19, 16, 18, 10, 11, 2, 13, 14, 3])# Divide by 2 and check if remainder is 1 又例如 cond = np.mod(array, 2)==1 cond output array([False, True, False, True, False, False, False, True, False, T...
