python选择排序

def choose_sort(raw_list):
    """对列表选择排序"""
    # 循环次数控制n-1
    for times in range(len(raw_list)-1):

        # 循环开始先假设第一个元素为最小值
        min_value = raw_list[times]

        # 遍历列表中的无序部分　如果元素小于min_value 就给min_value重新赋值
        if raw_list[times] < min_value:
            min_value = raw_list[times]

        # 最后将min_value 放到下标为times的位置上
        raw_list[times] = min_value
    print(raw_list)


if __name__ == ‘__main__‘:
    alist = [3, 1, 4, 5, 2, 1, 7]
    choose_sort(alist)
