Day 16 🧭行动：继续学习面对对象的开发 🤓体会：面向过程与面对对象的差别不小，目前还不知道代码更复杂点的面对对象方法的优势 🧑‍💻代码： # import math #学生类 class Student: def __init__(self,name,chinese,math,english): self.name = name self.chinese = chinese self.math = math self.english = english def __str__(self): return f"姓名{self.name} | 语文：{self.chinese} | 数学：{self.math} | 英语：{self.english} | 总分：{self.chinese + self.math + self.english}" #修改成绩 def update_score(self,chinese =None,math=None,english=None): if chinese is not None: self.chinese = chinese if math is not None: self.math = math if english is not None: self.english = english #教务管理系统 class Management: system_version = "1.0" system_name = "教务系统" def __init__(self): self.student_list = []#记录学生成绩 #增加 def add_student(self): name = input("请输入学生姓名: ") for s in self.student_list: if s.name == name: print("已存在该学生") return chinese = int(input("请输入学生语文成绩: ")) math = int(input("请输入学生数学成绩: ")) english = int(input("请输入学生英语成绩: ")) if 0 <= chinese <=100 and 0 <= math <= 100 and 0 <= english <= 100: stu = Student(name,chinese,math,english) self.student_list.append(stu) print("提交成功！") else: print("成绩不合理，无法添加") #删除 def delete_student(self): name = input("输入学生姓名：") for s in self.student_list: if s.name == name: self.student_list.remove(s) print("删除成功！") return print("未找到该学生，删除失败") #修改 def update_student(self): name = input("输入学生姓名：") for s in self.student_list: if s.name == name: print(f"当前成绩为：{s}") chinese = int(input("语文成绩：")) math = int(input("数学成绩：")) english = int(input("英语成绩：")) if 0 <= chinese <= 100 and 0 <= math <= 100 and 0 <= english <= 100: s.update_score(chinese,math,english) print("修改成功！") return else: print("成绩不合理，无法添加") return print("未找到该学生，修改失败") #查询 def query_student(self): name = input("输入学生姓名：") for s in self.student_list: if s.name == name: print(f"学生信息为{s}") return print("未找到该学生，查询失败") #展示全部学生信息 def list_student(self): for s in self.student_list: print(s) #运行系统 def run(self): print(f"欢迎使用教务管理系统 V{Management.system_version}") while True: print() print("# # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # #") print("# 1.添加学生 2.删除学生 3.修改学生 4.查询指定学生 5.查询所有学生 6.退出系统 #") print("# # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # #") print() choice = input("请选择要执行的操作，输入1-6:") match choice: case "1": # 添加学生 self.add_student() case "2": # 删除学生 self.delete_student() case "3": # 修改学生 self.update_student() case "4": # 查询指定学生 self.query_student() case "5": # 查询所有学生 self.list_student() case "6": print("Bye ~") break case _: print("无效指令") #测试 if __name__ == "__main__": management = Management() management.run()
