python快速排序代码实例

def sub_sort(array,low,high):
    key = array[low]
    while low         while low = key:
            high -= 1
        while low             array[low] = array[high]
            low += 1
            array[high] = array[low]
    array[low] = key
    return low

def quick_sort(array,low,high):
     if low         key_index = sub_sort(array,low,high)
        quick_sort(array,low,key_index)
        quick_sort(array,key_index+1,high)

if __name__ == '__main__':
    array = [8,10,9,6,4,16,5,13,26,18,2,45,34,23,1,7,3]
    print array
    quick_sort(array,0,len(array)-1)
    print array

结果：
[8, 10, 9, 6, 4, 16, 5, 13, 26, 18, 2, 45, 34, 23, 1, 7, 3]
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 13, 16, 18, 23, 26, 34, 45]
