numpy.
setxor1d
(ar1, ar2, assume_unique=False)[source]¶ Find the set exclusive-or of two arrays.
Return the sorted, unique values that are in only one (not both) of the input arrays.
Parameters: ar1, ar2 : array_like
Input arrays.
assume_unique : bool
If True, the input arrays are both assumed to be unique, which can speed up the calculation. Default is False.
Returns: setxor1d : ndarray
Sorted 1D array of unique values that are in only one of the input arrays.
Examples
>>> a = np.array([1, 2, 3, 2, 4]) >>> b = np.array([2, 3, 5, 7, 5]) >>> np.setxor1d(a,b) array([1, 4, 5, 7])
