常见模块作业

1、把登录与注册的密码都换成密文形式

import hashlib
m = hashlib.md5()
def register():
    inp_name = input("请输入账号：").strip()
    inp_pwd = input("请输入密码：").strip()
    re_inp_pw = input("请再次输入密码：").strip()
    if inp_pwd==re_inp_pw:
        m.update(inp_pwd.encode("utf-8"))
        res = m.hexdigest()
        # print(res)
        with open("a.txt","a",encoding="utf-8")as f:
            f.write(f'{inp_name}:{res}
')

def login():
    inp_name = input('输入账号').strip()
    inp_pwd = input('输入密码').strip()
    res = m.update(inp_pwd.encode('utf-8'))
    with open('a.txt','rt',encoding='utf-8')as f:
        for i in f:
            name,pwd = i.strip().split(':')
            if res == pwd and inp_name == name:
                print('登入成功')
                break
        else:
            print('登入失败')

2、文件完整性校验（考虑大文件）

import hashlib
m = hashlib.md5()
def a():
    with open("a.txt","rt",encoding="utf-8")as f :
        l = [10, 20, 30]
        for i in l :
            f.seek(i,0)
            res = f.read(100)
            m.update(res.encode("utf-8"))
        res = m.hexdigest()
        return res

def b():
    with open("b.txt","rt",encoding="utf-8")as f :
        l = [10,20,30]
        for i in l:
            f.seek(i,0)
            msg = f.read(5)
            m.update(msg.encode("utf-8"))
        res = m.hexdigest()
        if res == a():
            print("文件完整")
        else:
            print("文件不完整")

3、注册功能改用json实现

def register():
    inp_name = input("请输入账号：").strip()
    inp_pwd = input("请输入密码：").strip()
    re_inp_pw = input("请再次输入密码：").strip()
    if inp_pwd==re_inp_pw:
        with open("a.txt","a",encoding="utf-8")as f:
            json.dump(f'{inp_name}:{inp_pwd}',f)

4、项目的配置文件采用configparser进行解析

text.ini
[section1]
k1 = v1
k2:v2
user=egon
age=18
is_admin=true
salary=31
[section2]
k1 = v1

import configparser

config = configparser.ConfigParser()

config.read('text.ini')

print(config.sections())

print(config.options('section1'))

print(config.items('section1'))

res= config.get('section1','is_admin')

print(res,type(res))

print(config.getint('section1','age'))

print(config.getfloat('section1','age'))

print(config.getboolean('section1','is_admin'))
