sorted_arr = np.sort(arr)[::-1] 使用numpy.argsort和切片操作: python sorted_indices = np.argsort(arr)[::-1] sorted_arr_by_index = arr[sorted_indices] 打印排序后的数组: 最后,你可以打印排序后的数组来验证结果。 python print("Sorted array in descending order using np.sort and slicing...
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 the `numpy.argsort()` method in descending order in Python, negate the array before calling `argsort()`.

The numpy.argsort() method returns the indices that would sort an array. main.py import numpy as np arr = np.array([100, 50, 20, 30, 90, 1, 5]) # [5 6 2 3 1 4 0] print(arr.argsort()) The next step is to get the last N elements from the indices array. main.py impo...
Can I sort a 2-D array in descending order using numpy.argsort()? You can sort a 2-D array in descending order using numpy.argsort(). The key is to first get the sorted indices in ascending order, and then reverse these indices to obtain the descending order. How can I specify a ...
