python插入排序

def insertsort(list):    for i in range(1, len(list)):        temp = list[i]        for j in range(i, -1, -1):            if list[j] > temp:                list[j],list[j+1] = list[j+1], list[j]#python两值交换只要a,b=b,a即可，无需找中间值    return listprint insertsort([1, 4, 9, 13, 34, 26, 10, 7, 4])
