arr=np.array([3,1,4,2,5])arr.sort()arr=arr[::-1]print(arr) 1. 2. 3. 4. 5. 6. 代码分析: 首先导入Numpy库。 创建一个包含5个整数的数组arr。 使用sort函数对arr进行排序,默认是按照升序排序。 使用切片操作[::-1]将数组倒序排列。
numpy.sort(a[, axis=-1, kind='quicksort', order=None]) Return a sorted copy of an array. axis:排序沿数组的(轴)方向,0表示按列,1表示按行,None表示展开来排序,默认为-1,表示沿最后的轴排序。 kind:排序的算法,提供了快排'quicksort'、混排'mergesort'、堆排'heapsort', 默认为‘quicksort'。
