以下是一个使用 Python 类实现班级成员姓名成绩管理及每天出勤记录查看的程序： ```python import datetime class ClassManagement: def __init__(self): self.students = {} self.attendance_records = {} def add_student(self, name): if name not in self.students: self.students[name] = {'scores': [], 'attendance': {}} print(f"{name} 已添加到班级。") else: print(f"{name} 已存在于班级中。") def add_score(self, name, score): if name in self.students: self.students[name]['scores'].append(score) print(f"{name} 的成绩 {score} 已添加。") else: print(f"{name} 不在班级中，请先添加该学生。") def record_attendance(self, name, date=None): if date is None: date = datetime.date.today().strftime("%Y-%m-%d") if name in self.students: self.students[name]['attendance'][date] = True if date not in self.attendance_records: self.attendance_records[date] = [] self.attendance_records[date].append(name) print(f"{name} 在 {date} 的出勤已记录。") else: print(f"{name} 不在班级中，请先添加该学生。") def view_scores(self, name): if name in self.students: scores = self.students[name]['scores'] if scores: print(f"{name} 的成绩：{scores}") else: print(f"{name} 暂无成绩记录。") else: print(f"{name} 不在班级中，请先添加该学生。") def view_attendance(self, date=None): if date is None: date = datetime.date.today().strftime("%Y-%m-%d") if date in self.attendance_records: present_students = self.attendance_records[date] print(f"{date} 的出勤记录：{present_students}") else: print(f"{date} 暂无出勤记录。") # 主程序 class_manager = ClassManagement() while True: print("\n班级成员姓名成绩管理程序") print("1. 添加学生") print("2. 添加学生成绩") print("3. 记录学生出勤") print("4. 查看学生成绩") print("5. 查看某天的出勤记录") print("6. 退出") choice = input("请输入你的选择：") if choice == '1': name = input("请输入学生姓名：") class_manager.add_student(name) elif choice == '2': name = input("请输入学生姓名：") score = float(input("请输入学生成绩：")) class_manager.add_score(name, score) elif choice == '3': name = input("请输入学生姓名：") class_manager.record_attendance(name) elif choice == '4': name = input("请输入学生姓名：") class_manager.view_scores(name) elif choice == '5': date = input("请输入日期（格式：YYYY-MM-DD，留空则查看今天）：") if date == '': date = None class_manager.view_attendance(date) elif choice == '6': print("程序已退出。") break else: print("无效的选择，请重新输入。") ```
