希望你能得到附加python程序的建议。我们可以使用字典作为数据库,用于非常基本的登录系统程序吗?

我正在尝试创建登录系统程序,其中“姓名”、“电子邮件”和“密码”必须从用户处作为输入,并保存为文本文件中的字典。我被困在如何给每个命题分配一个变量上。 此外,一旦用户注册后再次出现,应该对字典文本文件进行密码检查,我不确定。请查看下面的代码并提供帮助?

#! usr/bin/python3
# Login project sample
import json
def login():

    print("Welcome to login system")
    New_user = input("Are you a new user? type yes or no: ")
    if New_user == "yes":
        a = {}
        Name = input("Enter your name: ")
        Email = input("Enter the email: ")
        Password = input("Enter the password: ")
        a["Name"] = (Name)
        a["Email"] = (Email)
        a["Password"] = (Password)
        print(a)
        with open("login.txt", "a+") as f:
            f.seek(0)
            data = f.read(100)
            if len(data) > 0:
                f.write("\n")
                x = str(range(1,100))
                f.write(x + "=" + json.dumps(a))
                x = x + 1
    else:
        b={}
        def login1():

            Email = input("Enter the email: ")
            Password = input("Enter the password: ")
            b["Email"] = (Email)
            b["Password"] = (Password)
            with open("login.txt", "r") as r:
                f.seek(0)
                i = range(100)
                if i.keys() in b.keys() and i.value() in b.value():
                    print("Login is successfull")
                else:
                    login1()
login()
