numpy.intersect1d(ar1, ar2, assume_unique=False, return_indices=False)[source]Find the intersection of two arrays. 返回两个数组中共同的元素 Return thesorted, uniquevalues that areinboth of the input arrays. 注意:是排序后的 Pa
If you want to get the intersection of two arrays, use theintersect1d()method in Numpy. Intersection means finding common elements between two arrays. In this lesson, we will see some examples: Find the intersection between two arrays
numpy.intersect1d(ar1, ar2, assume_unique=False, return_indices=False) Find the intersection of two arrays. x = np.array([1, 1, 2, 3, 4]) y = np.array([2, 1, 4, 6]) xy, x_ind, y_ind = np.intersect1d(x, y, return_indices=True) print(x_ind) print(y_ind) print(xy...
Find intersection of the following two set arrays: importnumpyasnp arr1 = np.array([1,2,3,4]) arr2 = np.array([3,4,5,6]) newarr = np.intersect1d(arr1, arr2, assume_unique=True) print(newarr) Try it Yourself » Note:theintersect1d()method takes an optional argumentassume_uni...
numpy.intersect1d(ar1, ar2, assume_unique=False, return_indices=False)[source]Find the intersection of two arrays. 返回两个数组中共同的元素 找到2个数组中集合元素的差异 setdiff1d(ar1, ar2, assume_unique=False) 1.功能:找到2个数组中集合元素的差异。
