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...
A custom key function can be supplied to customize the sort order, and the reverse flag can be set to request the result in descending order. In [2]: help(list.sort) Help on method_descriptor: sort(...) L.sort(key=None, reverse=False) -> None -- stable sort *IN PLACE* # 一维...

To use np.argsort in descending order in Python, first apply np.argsort to our array, and then either invert the result using array slicing ([::-1]) or negate the array before sorting. For inverting, sort the array using np.argsort and then reverse the resulting indices. For negating, ...
