python实现快排算法，传统快排算法，数据结构

def quick_sort(lists,i,j):
    if i >= j:
        return list
    pivot = lists[i]
    low = i
    high = j
    while i < j:
        while i < j and lists[j] >= pivot:
            j -= 1
        lists[i]=lists[j]
        while i < j and lists[i] <=pivot:
            i += 1
        lists[j]=lists[i]
    lists[j] = pivot
    quick_sort(lists,low,i-1)
    quick_sort(lists,i+1,high)
    return lists

if __name__=="__main__":
    lists=[30,24,5,58,18,36,12,42,39]
    print("排序前的序列为：")
    for i in lists:
        print(i,end =" ")
    print("
排序后的序列为：")
    for i in quick_sort(lists,0,len(lists)-1):
        print(i,end=" ")

>>>
排序前的序列为：
30 24 5 58 18 36 12 42 39
排序后的序列为：
5 12 18 24 30 36 39 42 58
