2023年3月青少年软件编程Python等级考试试卷四级真题及答案解析
2023年3月青少年软件编程Python等级考试试卷四级真题(含答案解析)分数:100 题数:38一、单选题(共25题,共50分)。
1.运行下列程序,输出的结果是(B)。
A. helloB. hellozhejiangC. hellonameD. 程序将提示运行错误解析:定义函数时,可以指定形参的默认值。
如果在调用函数时给函数提供了实参,Python将使用指定的实参,否则将自动调用形参的默认值。
本题中,调用wenhao函数时没有传值,故使用函数的默认值作为函数的调用。
2.运行下列程序,输出的结果是(C)。
A. 5B. 15C. 25D. 35解析:rst(5)传入一个实参,a被赋值为5,b使用默认值5,因此结果是5*5=25,选C。
3.运行下列程序,输出的结果是(C)。
A. 3.14B. 因缺失参数,不能计算。
C. NoneD. 程序代码有错误解析:函数jsarea中,没有return语句,函数中计算的结果area不能传递给函数调用处,因此调用函数的结果是None。
4.运行下列程序,输出的结果是(D)。
A. 20230110B. 01103202C. 2301102D. 1103202解析:函数js的功能是计算n的逆序数,因此选D。
5.在传递信息的过程中,通常会将一些敏感信息进行加密,以下是对数据进行加密的Python程序段,若输入数据为“cie0108”,则输出的结果是(C)。
A. 1343eicB. 0108cieC. cie3431D. 3431cie解析:函数jm中对原文进行处理,若是字母,不变,累加;若是数字,转为整型加3然后求其个位上的数,因此答案是cie3431,选C。
6.运行下列程序,输出的结果是(B)。
A. 3B. 6C. 9D. 0解析:在函数f中,变量s定义为global全局变量,第一次调用f(3)后返回的结果是3,此时变量s的值变成3,再次调用函数f(3)时,因s的初值已经是3了,因此结果是6。
2024年3月青少年软件编程Python等级考试试卷四级真题(含答案和解析)
2024年3月青少年软件编程Python等级考试试卷四级真题(含答案和解析)分数:100 题数:38一、单选题(共25题,共50分)。
1. 运行如下代码,若输入整数3,则最终输出的结果为?()def f(x):if x==1:s=1else:s=f(x-1)*xreturn sn=int(input("请输入一个大于1的整数:"))print(f(n)+f(n-1))A. 2B. 4C. 8D. 16标准答案:C。
试题解析:由于f(3)=f(2)*3,f(2)=f(1)*2,f(1)=1,所以f(3)+f(2)=6+2=8。
2.运行下列程序,输出的结果是?()def fun(x):if x > 3:return x * fun(x-1)else:return xprint(fun(6))A. 120B. 360C. 720D. 60标准答案:B。
试题解析:递归函数求解,根据递归函数6*5*4*3=360。
3. 下列关于递归的描述不正确的是?()A. 递归函数一定包含if语句。
B. 递归函数体内一定包含调用自身的语句。
C. 在调用自身函数时需要明确的边界终止条件与边界值。
D. 递归算法一般代码简洁,执行效率高,空间复杂度低。
标准答案:D。
试题解析:递归算法一般代码简洁,易于理解,但执行效率较低,空间复杂度高。
4. 运行下列程序,输出的结果是?()def fun(a, n):s = 0for i in range(1, n+1):temp = str(a)*is += int(temp)return sprint(fun(1, 3))A. 3B. 6C. 12D. 123标准答案:D。
试题解析:递推函数求解,本题是求1+11+111之和。
