举个例子,下面是用Python实现的经典的quicksort算法例子: defquicksort(arr):iflen(arr) <=1:returnarr pivot = arr[len(arr) /2] left = [xforxinarrifx < pivot] middle = [xforxinarrifx == pivot] right = [xforxinarrifx > pivot]returnquicksort(left) + middle + quicksort(right)printqui...
defquicksort(arr):iflen(arr)<=1:returnarrpivot=arr[len(arr)/2]left=[xforxinarrifx<pivot]middle=[xforxinarrifx==pivot]right=[xforxinarrifx>pivot]returnquicksort(left)+middle+quicksort(right)printquicksort([3,6,8,10,1,2,1])# Prints "[1, 1, 2, 3, 6, 8, 10]" Python 版本 ...
We expect that many of you will have some experience with Python and numpy; for the rest of you, this section will serve as a quick crash course both on the Python programming language and on the use of Python for scientific computing. Some of you may have previous knowledge in Matlab, ...
作为一个例子,这里是在Python经典的快速排序算法的实现: defquicksort(arr):iflen(arr)<=1:returnarr pivot=arr[len(arr)//2]left=[xforxinarrifx<pivot]middle=[xforxinarrifx==pivot]right=[xforxinarrifx>pivot]returnquicksort(left)+middle+quicksort(right)print(quicksort([3,6,8,10,1,2,1])...
