array([1, 2, 0]) Two-dimensional array:二维数组 >>> x = np.array([[0, 3], [2, 2]]) >>> x array([[0, 3], [2, 2]]) >>> np.argsort(x, axis=0) #按列排序 array([[0, 1], [1, 0]]) >>> np.argsort(x, axis=1) #按行排序 array([[0, 1], [0, 1]]) #...
argsort(a, axis=-1, kind='quicksort', order=None) Returns the indices that would sort an array. 从中可以看出argsort函数返回的是数组值从小到大的索引值 Examples --- One dimensional array:一维数组 >>> x = np.array([3, 1, 2])>>>np.argsort(x) array([1, 2, 0]) Two-dimensional a...

(two-dimensional array), even if you use the slicing method to copy list2 and modify the elements in list2, list1 will still be changed. Because the elements in the list, such as list1[0], are a list, an object, and a reference. If you look at the memory addresses of the two,...
