太原理工大学2018级python复习题

第一题：

# 题目要求 键盘输入字符串 对其每个不重复的字符串形成列表 倒序输出
str_ = input("请输入字符串")
# 把字符串转为列表
listt = list(str_)
# 使用切片完成倒序
listtt = listt[::-1]
# 使用列表推导式去重
list3 = []
[list3.append(i) for i in listtt if not i in list3]
print(list3)

第二题

# 求阶乘的和
sum_test = 0


def test_sum(n):
    if n == 1:
        return 1
    return n * test_sum(n - 1)


n = int(input("请输入n的值"))
for i in range(1,n+1):
    sum_test += test_sum(i)
print(sum_test)

第三题：

class teacher(object):
    def __init__(self, title, major, subject):
        self.title = title
        self.major = major
        self.subject = subject

    def printTeacherInfo(self):
        print(f"教室的职称是{self.title}教师的专业是{self.major}教师的授课名称是{self.subject}")


class Cadre(object):
    def __init__(self, postion, department):
        self.posttion = postion
        self.department = department

    def printCadreInfo(self):
        print(f"干部的职位是{self.posttion}干部的部门是{self.department}")


class TeacherCadre(teacher, Cadre):
    def __init__(self, title, major, subject, postion, dpartment, name, gender, age, wages):
        teacher.__init__(self, title, major, subject)
        Cadre.__init__(self, postion, dpartment)
        self.name = name
        self.gender = gender
        self.age = age
        self.__wages = wages

    def printTeacherCadreInfo(self):
        print(f"职称是{self.title}专业是{self.major}授课名称是{self.subject}职位是{self.posttion}"
              f"部门是{self.department}姓名是{self.name}年龄是{self.age}性别是{self.gender}工资是{self.__wages}")


teacherCadre = TeacherCadre("老师", "软件", "数据库", "牛皮", "教学部", "libin", "男", 22, 5000)
teacherCadre.printTeacherCadreInfo()

第四题

# coding=utf-8
# 一个学校，有3个办公室，现在有8位老师等待工位的分配，请编写程序，完成随机的分配.
import random

# 定义一个列表来保存3个办公室
offices = [[], [], []]

# 定义一个列表来存储8位老师的名字
names = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H']

# 开始分配
# for name in names:
# index = random.randint(0, 2)
# offices[index].append(name)
# 如果有一个办公室为空就重新分配
while len(offices[0]) == 0 or len(offices[1]) == 0 or len(offices[2]) == 0:
    for name in names:
        index = random.randint(0, 2)
        offices[index].append(name)
# 遍历输出分配结果
i = 1
for tempNames in offices:
    print('办公室%d中有%d个老师，分别是：' % (i, len(tempNames))),
    i += 1
    for name in tempNames:
        print('%s' % name, end=" "),
    print()
