目录结构:
1、 学生文件 student.py
# 学生类 class Student(object): # 存放学生信息 student_info = {} # 学生初始化方法 def __init__(self,id,name,addr,tel): self.id = id self.name = name self.addr = addr self.tel = tel # 将学生的信息添加到学生信息字典里 self.student_info["学号"] = self.id self.student_info["姓名"] = self.name self.student_info["地址"] = self.addr self.student_info["电话"] = self.tel
2、 管理系统文件 manager.py
import json import student # 管理系统类 class Manager(object): # 展示所有学生信息的方法 def show_all_student(self): with open("students_info.json", mode="r", encoding="utf8") as f: content = json.loads(f.read()) if content: print("所有的学生信息如下:") print("#######################################") for stu in content: print(stu) print("#######################################") elif len(content) == 0: print("Sorry! 一个学生都没有!") # 添加学生的方法 def add_student(self): print("~~~~~~~~~~~~~~~~~~~~将要开始添加学生信息~~~~~~~~~~~~~~~~~~~~~") id = input("请输入学号:") name = input("请输入姓名:") addr = input("请输入地址:") tel = input("请输入电话:") new_student = student.Student(id, name, addr, tel) with open("students_info.json", mode="r", encoding="utf8") as f1: content = json.loads(f1.read()) new_content = list(content) new_content.append(new_student.student_info) json_content = json.dumps(new_content) with open("students_info.json",mode="w",encoding="utf8") as f2: f2.write(json_content) print("~~~~~~~~~~~~~~~~~~~~!!!添加完成!!!~~~~~~~~~~~~~~~~~~~~~") # 删除学生的方法 def delete_student(self): print("~~~~~~~~~~~~~~~~~~~~将要开始添加学生信息~~~~~~~~~~~~~~~~~~~~~") id = input("请输入要删除的学生的学号:") with open("students_info.json",mode="r",encoding="utf8") as f: content = list(json.loads(f.read())) for item in content: if item["学号"] == id: content.remove(item) json_content = json.dumps(content) with open("students_info.json", mode="w", encoding="utf8") as f2: f2.write(json_content) print("~~~~~~~~~~~~~~~~~~~~!!!删除成功!!!~~~~~~~~~~~~~~~~~~~~~") return print("输入的学号不存在!!!") # 修改学生的方法 def update_student(self): print("~~~~~~~~~~~~~~~~~~~~开始修改学生信息~~~~~~~~~~~~~~~~~~~~~") with open("students_info.json", mode="r", encoding="utf8") as f: text = list(json.loads(f.read())) delete_number = input("请输入要修改的学生学号:") for i in text: if i["学号"] == delete_number: new_addr = input("请输入修改后的地址:") new_tel = input("请输入修改后的电话:") i["地址"] = new_addr i["电话"] = new_tel json_text = json.dumps(text) with open("students_info.json", mode="w", encoding="utf8") as f2: f2.write(json_text) print("~~~~~~~~~~~~~~~~~~~~修改成功~~~~~~~~~~~~~~~~~~~~~") return print("输入的学号不存在!!!!!!!!!!!!!") # 系统启动入口方法 def system_start(self): while True: print("########### 欢迎来到学生管理系统 ############") print("################ 请登录系统 ################") user_name = input("请输入用户名: ") pass_word = input(" 请输入密码: ") if user_name == "zyh" and pass_word == "123456": print("################ 登陆成功!################") break else: print("登录信息错误,请重新登录!") while True: print("################ 你已经进入学生管理系统 ################") print("###################### 请选择功能 ######################") print("1. 展示所有学生信息") print("2. 添加学生") print("3. 删除学生") print("4. 修改学生") print("5. 退出系统") print("#######################################################") while True: choice = int(input("请输入功能对应的序号(1/2/3/4/5/6): ")) if choice == 1: # print("调用展示所有学生信息的方法") self.show_all_student() break elif choice == 2: # print("调用添加学生的方法") self.add_student() break elif choice == 3: # print("调用删除学生的方法") self.delete_student() break elif choice == 4: # print("调用修改学生的方法") self.update_student() break elif choice == 5: print("退出学生管理系统!!!!!!!!!!!") return else: print("输入信息不合法,请重新输入!")
3、 程序入口文件 main.py
import manager if __name__ == '__main__': manager_sys = manager.Manager() manager_sys.system_start()
4、 学生信息文件 students_info.json
[ {"学号": "0001", "姓名": "张三", "地址": "北京", "电话": "13244453359"}, {"学号": "0002", "姓名": "张三2", "地址": "北京", "电话": "13244453359"}, {"学号": "0003", "姓名": "张三3", "地址": "北京", "电话": "13244453359"}, {"学号": "0004", "姓名": "张三4", "地址": "北京", "电话": "13244453359"} ]
