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 theinput arrays.

Parameters:	ar1, ar2:array_like Input arrays. assume_unique:bool If True, the input arrays are both assumed to be unique, whichcan speed up the calculation. Default is False.
Returns:	setxor1d:ndarray Sorted 1D array of unique values that are in only one of the inputarrays.

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])
