import numpy as np # 创建一个numpy数组 arr = np.array([3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5]) # 使用numpy的sort函数对数组进行排序,并通过切片操作实现逆序排序 sorted_arr_desc = np.sort(arr)[::-1] # 输出排序后的数组 print("Sorted array in descending order using slicing:", so...
Sorting a NumPy array in descending order sorts the elements from largest to smallest value. You can use the syntaxarray[::-1]to reverse the array. # Sort array in descending orderarray=np.sort(array)[::-1]print("Sorted descending order:\n",array)# Output# Sorted descending order:# [...
>>> s = sorted(student_objects, key=attrgetter('age'))#sort on secondary key>>> sorted(s, key=attrgetter('grade'), reverse=True)#now sort on primary key, descending[('dave','B', 10), ('jane','B', 12), ('john','A', 15)] 6)numpy中数组矩阵的排序方法argsort() argsort(a, ...
