学生管理系统

  • 1.首先新建一个index.py和student_manager.py文件
  • 2.新建一个file_manager.py 文件
  • 3.新建一个model.py
  • 4.新建一个tools类
  • 5.在当前目录下面新建一个files文件夹存放文件
  • 6.开始刺激的填充代码


  • 先看看效果

  • 结果图
  • 文件路径

1.首先新建一个index.py和student_manager.py文件

用来写本系统的基本思路，然后慢慢的填充代码

def register():
	pass


def login():
	pass

def start():
    content = file_manager.read_file('welcome.txt')
    while True:
        operator = input(content + '\n请选择（1~3）：')
        if operator =='1':
            login()
            print('登录')
        elif operator =='2':
            register()
            print('注册')
        elif operator =='3':
            # break #把死循环停止
            exit(0) #结束程序
        else:
            print('输入有误')


    # 读文件
    # try:
    #     with open('files/welcome.txt', 'r', encoding='utf-8') as file:
    #         content = file.read()
    #         while True:
    #             input(content)
    # except FileNotFoundError:
    #     print('文件未找到')
    #

if __name__ == '__main__':
    start()

def add_student():
    pass
def show_student( ):
     pass

def modify_student():
        pass
def delte_student():
        pass
def show_manager():
    content = file_manager.read_file('student.txt')%name
    while True:
        print(content)
        operator = input('请选择功能(1~5):')
        if operator == '1':
            add_student()
        elif operator == '2':
            show_student()
        elif operator == '3':
            modify_student()
        elif operator == '4':
            delte_student()
        elif operator == '5':
            break
        else:
            print('输入有误')
2.新建一个file_manager.py 文件

由于读写文件经常使用，将文件读写放在一个类中方便调用，需要的有如下三个

'''
文件管理类
读文件
read_file 读TXT文件
write_json写json文件
read_json 读json文件
'''

base_dir = './files/'

def read_file(file_name):
    try:
        with open(base_dir+file_name,'r',encoding='utf-8') as file:
            content = file.read()
            return content
    except FileNotFoundError:
        print('文件未找到')

def write_json(file_name,data):
    with open(base_dir+file_name,'w',encoding='utf8') as file:
        import json
        json.dump(data,file)

def read_json(file_name,default_data):
    try:
        with open(base_dir+file_name,'r',encoding='utf-8') as file:
            import json
            return json.load(file)
    except FileNotFoundError:
        return default_data
3.新建一个model.py

用于创建对象，需要的如下

'''
model 类
用于创建对象
'''
class Teacher(object):
    def __init__(self,name,password):
        import tools
        self.name = name
        self.password =tools.encrypt_password(password)

class Student(object):
    def __init__(self,s_id,name,age,gender,tel):
        self.s_id = s_id
        self.name = name
        self.age = age
        self.gender = gender
        self.tel = tel
4.新建一个tools类

用来加密密码

'''
工具类
encrypt_password  加密
'''
import hashlib
def encrypt_password(passwd,x='ztwztw'):
    h = hashlib.sha256()
    h.update(passwd.encode('utf8'))
    h.update(x.encode('utf8'))
    return h.hexdigest()
5.在当前目录下面新建一个files文件夹存放文件

6.开始刺激的填充代码

由于比较多，就不一一展示填充了

    while True:

        if not  3 <= len(teacher_name) <= 6:
            print('输入账号不符合要求 请重新输入')
        else:
            break
    if teacher_name in data:
        print('注册失败 该账号已注册')

    while True:
        password = input('请输入密码（6~12位）:')
        if not  6 <= len(password) <= 12:
            print('输入账号不符合要求 请重新输入')
        else:
            break

  
    t = model.Teacher(teacher_name,password)

    data[t.name] = t.password

        return

        student_manager.name = teacher_name
        student_manager.show_manager()
        print('登录成功')

    else:
        print('登录失败')

    while True:
        operator = input(content + '\n请选择（1~3）：')
