    If you are trying to divide every element of x by 2, then the following will do it:

    x = np.array([2, 4, 6, 8, 10])
    x /= 2
    

    The resulting value of x is array([1, 2, 3, 4, 5]).

    Note that the above uses integer (truncating) division. If you want floating-point division, either make x into a floating-point array:

    x = np.array([2, 4, 6, 8, 10], dtype='float64')
    

    or change the division to:

    x = x / 2.0
