代码与参考答案不一定相同，但结果一致，真题更新顺序不一定规律

基础操作

1-1

s = input("请输入一个字符串:")
print("{:=^20}".format(s))

1-2

a, b = 0, 1
while a < 100:
    print(a, end=',')
    a, b = b, a+b

1-3

import jieba
jieba.setLogLevel(jieba.logging.INFO)
txt = input("请输入一段中文文本:")
ls = jieba.lcut(txt)
for i in ls[::-1]:
    print(i, end='')

简单应用

2-1

import turtle as t
for i in range(3):
    t.seth(i*120)
    t.fd(200)

2-2

data = input()  # 课程名 考分
ls = data.split()
maxName = ls[0]
maxScore = eval(ls[1])
minName = ls[0]
minScore = eval(ls[1])
sum = 0
n = 0

while data:
    n += 1
    ls = data.split()
    if maxScore < eval(ls[1]):
        maxScore = eval(ls[1])
        maxName = ls[0]
    if minScore > eval(ls[1]):
        minScore = eval(ls[1])
        minName = ls[0]
    sum += eval(ls[1])
    data = input()

avg = sum/n
print("最高分课程是{} {}, 最低分课程是{} {}, 平均分是{:.2f}".format(
    maxName, maxScore, minName, minScore, avg))
