如何检查一个文档中的一行是否适用于同一行，但在另一个文档中

Question

我以前的问题已经通过在某些地方使用类而不是函数来解决。但是还有一个问题。如何检查一个文档中的一行是否适用于同一行但在另一个文档中？我试过这个，它什么也没做，也没有给我错误代码。

class Logging1(object):

    def __init__(self, enteruser, enterpass):
        self.enteruser = enteruser
        self.enterpass = enterpass

    def __call__(self):

        usernames1 = open("usernames.txt", "r")
        passwords2 = open("passwords.txt", "r")

        rowU = 0
        rowP = 0

        for x in usernames1:
            if x != self.enteruser.get():
                rowU += 1
            else:
                break

        for y in passwords2:
            if y != self.enterpass.get():
                rowP += 1
            elif rowP == rowU:
                logged = Label(root, text="Successful login!")
                logged.grid(row=5, column=1)
                break

Answer 1

在调用函数时没有传递这两个变量regEnterpass, regEnteruser

由于我在平板电脑上，我无法进行测试，但以下操作是否有效？通过创建一个类来存储两个变量并在调用时使用它们

更新：您可以读取 init 中的文本文件并将它们存储为字典

class Logging1(object):

    def __init__(self, enteruser, enterpass):
        self.enteruser = enteruser
        self.enterpass = enterpass
        
        ## open usernames.txt and get usernames
        with open("usernames.txt", "r") as users_file:
            users = [user for user in users_file]

        ## open password.txt and get passwords
        with open("passwords.txt", "r") as password_file:
            passwords = [password for password in password_file]
        
        ## combine and store them in a dictionary 
        self.users_dict = dict(zip(users, passwords))

    def __call__(self):
        entered_user = self.enteruser.get() ## get entered username
        
        if self.users_dict.has_key(entered_user): ## valid username
            entered_pw = self.enterpass.get() ## get entered password
            
            stored_pw = self.users_dict[entered_user]
            
            if entered_pw == stored_pw: ## correct username and pw
                logged = Label(root, text="Successful login!")
                logged.grid(row=5, column=1)
            else: 
                pass ## incorrect password
                
        else: pass ## not a valid username
        
def register():

    regUsername = Label(root, text="Set username: ")
    regUsername.grid(row=0, column=0)
    regEnteruser = Entry(root)
    regEnteruser.grid(row=0, column=1)

    regPassword = Label(root, text="Set password: ")
    regPassword.grid(row=1, column=0)
    regEnterpass = Entry(root)
    regEnterpass.grid(row=1, column=1)
    
    registering1 = Logging1(regEnterpass, regEnteruser) ## create Registering1 object

    buttonreg = Button(root, text="Register", padx="30", pady="5", command=registering1)
    buttonreg.grid(row=2, column=1)

    return regEnterpass and regEnteruser
