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...
Sort NumPy in Descending order To sort a NumPy array in descending order (from largest to smallest), we will still usenp.sort(), but we will reverse the order of the sorted array. descending_arr = np.sort(arr)[::-1] print("Array in Descending Order:", descending_arr) Output: Array...

How can I sort a 2-D array using numpy.argsort()? You can sort a 2-D array usingnumpy.argsort()by specifying theaxisparameter. Sorting along rows or columns can be achieved by setting theaxisparameter accordingly. Can I sort a 2-D array in descending order using numpy.argsort()?
不清楚你想用脚本实现什么,但基本上,如果你.ToString(..)是一个DateTime对象,那么Sort-Object将不知道如何正确排序。以下是如何处理代码: $DCs = (Get-ADDomainController -Filter *).Name$users = @'samaccountname;user1user2'@ | ConvertFrom-Csv -Delimiter ';'& { foreach ($DC in $DCs) { foreach...
