numpy.setxor1d()

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:

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.

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.

>>> 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])
