I am writing some code for a login system in python and I can't seem to be able to have it read the email and password from a txt file

import hashlib
def signup():
email = input("Enter an email address: ")
pwd = input("Enter a password: ")
conf_pwd = input("Confirm your password: ")
if conf_pwd == pwd:
enc = conf_pwd.encode()
hash1 = hashlib.sha256(enc).hexdigest()
with open(r'D:\Python Programs\Login\database.txt', "a") as f:
f.write(email + "\n")
f.write(hash1 + "\n")
f.close()
print("You have registered successfully!")
else:
print("Password is not same as above! \nPlease try again")
signup()
def login():
email = input("Enter email: ")
pwd = input("Enter password: ")
auth = pwd.encode()
auth_hash = hashlib.sha256(auth).hexdigest()
with open(r'D:\Python Programs\Login\database.txt', "r") as f:
stored_email, stored_pwd = f.read().split("\n")
f.close()
if email == stored_email and auth_hash == stored_pwd:
print("Logged in Successfully!")
else:
print("Login failed! \nPlease try again")
login()
def welcome():
print("Welcome to the [Insert Game Name Here]")
HaveAccount = input("Have you made an account before? (Y/N): ")
if HaveAccount == ("Y"):
login()
elif HaveAccount == ("N"):
signup()
else:
print("Please enter either 'Y' or 'N'")
welcome()
welcome()
It is specifically line 23 and it has a ValueError: too many values to unpack (expected 2) whenever I try and log in with an email and password. I need to add some extra text in because my post is mostly code and I don't know what else to say so here is some random typing to make more characters in my post. Any help is appreciated. Thanks

How to edit a cell using and saving it to a file pandas (Python)

I need help, I don't know hot wo change the value of a cell and save it to the file. I just want to make it so when the user has verified the o changes to 1 in the verified column. The information looks weird because it is encrypted. All of the code for verification and cell stuff can be found in the Verify() function.
The csv file:
The whole code:

Use df.loc[desired_row, desired_column] = specified_value to set the value, and use pd.to_excel(desired_file_name) to save the file.

I fix it just had to subtract 2 from the line number to get to the right line in the verify function.
LineNumber -= 2

Account creation program is not reading file properly

I've been making a program that allows the user to create an account which saves to a txt file, and allows them to login. The text now saves to the file (which I was unable to make work earlier due to using w+ instead of a+) but I am not quite sure I understand how split() works. When I try to use the info saved to the txt file the program returns that the username cannot be found. If anyone could fix this code id appreciate it.
I began a few weeks ago so a lot of this is new to me.
AccountsFile = open("AccountProj.txt", "a+")
AccountList = [line.split('\n') for line in AccountsFile.readlines()]
#Creates an account
def createaccount():
while True:
newname = (input("Please create a username: "))
if newname in AccountsFile:
print("Username already in use.")
continue
elif newname not in AccountsFile:
newpassword = input("Please create a password: ")
checkpassword = input("Re-enter password: ")
if checkpassword == newpassword:
print("Account Sucessesfuly created!")
AccountsFile.write(newname + '\n')
AccountsFile.write(checkpassword + '\n')
AccountsFile.close()
break
elif checkpassword != newpassword:
print("Passwords do not match")
continue
#Logs into an account
def loginaccount():
while True:
username_entry = input("Enter username: ")
if username_entry not in AccountList:
print("Username not found. Please enter a valid name")
continue
if username_entry in AccountList:
password_entry = input("Enter password: ")
if password_entry in AccountList[AccountList.index(username_entry) + 1]:
print("Login sucessful!")
AccountsFile.close()
break
if password_entry not in AccountList[AccountList.index(username_entry) + 1]:
print("Username and password do not match. Please try again.")
AccountsFile.close()
continue
while True:
#Asks if user wants to create or login to an account
loginchoice = input("Would you like to login? (Y/N) ")
if loginchoice in ('Y', 'N'):
if loginchoice == 'Y':
loginaccount()
if loginchoice == 'N':
createchoice = str(input("Would you like to create an account? (Y/N) "))
if createchoice in ('Y', 'N'):
if createchoice == 'Y':
createaccount()
if createchoice == 'N':
pass
break
else:
print("Invalid Input")

def CreateAccount():
Username = input("Username: ") #Enter Username
Username.replace(" ", "") #Removes spaces (Optional)
AppValid = True #Default value that changes if duplicate account found
File = open("Accounts.txt","r") #Checking if username already exits
for Line in File:
Account = Line.split(",")
if Account[0] == Application:
print("There is already an Account with this Username")
AppValid = False #Changing value if username exits
File.close()
if AppValid == True: #If username not found, carries on
Password = input("Password: ") #Asks for Password
CheckPassword = input("Password: ")
if Password == CheckPassword:
print("Password's Match!") #Password Match
else:
print("No match")
File = open("Accounts.txt","a") #Writing new account to File
File.write(Username + "," + Password + "\n")
File.close()
def ViewAccount(Username, Password):
File = open("Accounts.txt","r")
Data = File.readlines()
File.close()
if len(Data) == 0:
print("You have no Accounts") #Account not found since no accounts
else:
AccountFound = false
for X in Data: #Looping through account data
if X[0] == Username: #Username match

if AccountFound = false:
print("Account not FOUND")
Theres some code i threw together (JK my hand hurts from typing that and my keyboard is screaming) but back to the point .split(" ") would split a string into a list based on spaces for that example, eg:
String = "Hello There"
String = String.split(" ") #Or String.split() only owrks for spaces by default
print("Output:", String[0]) #Output: Hello
print("Output:", String[1]) #Output: There
String = "Word1, Word2"
String = String.split(", ") #Splits string by inserted value
print("Output:", String[0]) #Output: Word1
print("Output:", String[1]) #Output: Word2
String = "abcdefghijklmnop"
String = String.split("jk") #Splits string by inserted value
print("Output:", String[0]) #Output: abcdefghi
print("Output:", String[1]) #Output: lmnop

Check AccountList - both split() and readlines() create a list for you, so you have a list of lists and your username_entry check can't work that way.

Is there a reason why the program is not able to compare the users input and the file?

I cannot see a reason why my program isnt able to compare the users input and such. My program is a Username/Password program for a OS i am working on i am not sure why it isnt working it always fires back with incorrect even when it is correct?
import os
isuserempty = os.stat("Username.txt").st_size == 0
ispassempty = os.stat("Password.txt").st_size == 0
if isuserempty or ispassempty == True:
print("Hello, new user create a username and password.")
newusername = input("Enter your new username: ")
NewUser = open("Username.txt" , "a")
NewUser.write(newusername)
NewUser.close()
newpassword = input("Enter your new password: ")
NewPass = open("Password.txt" , "a")
NewPass.write(newpassword)
NewPass.close()
print("You now have a new Username and Password!")
print("You are now logged in!")
elif isuserempty or ispassempty == False:
truePass = open("Password.txt", "r")
trueUser = open("Username.txt", "r")
print("Enter your Username.")
userUserName = input("Enter:")
print("Enter your password.")
userPass = input("Enter:")
if userUserName == trueUser and userPass == truePass:
print("Correct! Logging in...")
if userUserName != trueUser or userPass != truePass:
print("Incorrect!")

Your truePass and trueUser are variables of type TextIOWrapper (files) which you currently compare to strings. In your elif block, read the contents of your files like this before doing the comparison.
pass_file = open("Password.txt", "r")
truePass=pass_file.read()
user_file = open("Username.txt", "r")
trueUser = user_file.read()

I am having trouble writing into a text file because it says my line should be an str and not an int

print("Welcome to English, please enter your name,age,and password.")
print("If you have previously signed in, enter using the same name,age,and password")
name = input("Please enter your name: ")
age = input("Now please enter you age: ")
username = name[0:3] + age
password = input("Now please create a password: ")
userpass = (username+","+password)
check = open("logins.txt")
string = check.read().strip().split()
if userpass in string:
print("You have logged in as",username,"The questions will now start. \n")
else:
newlog = input("Looks like you dont have an account with those details, Would you like to create a new one? Y/N: ")
if newlog == "Y" or newlog == "y" or newlog == "yes" or newlog == "Yes":
f = open("logins.txt","a+")
chosen = f.write(username+","+password+"\n")
print("The username",username,"and password",password,"have now been saved, the questions will now start \n")
f.close()
else:
print("Please either sign in or log in and try again.")
welcome()
import random
f = open("English.txt","r")
points = 0
for line in f:
currentLine = line.split(",")
q = currentLine[0]
answer = currentLine[1]
questions = currentLine[1:-1]
random.shuffle(questions)
print(q)
for i in range(len(questions)):
print (i+1,":",questions[i])
userAnswer = int(input("Make a selection :"))
if answer == questions[userAnswer-1]:
points = (points+1)
print ("CORRECT, You have",points,"points")
str(points)
else:
print ("INCORRECT")
f.close()
f = open("scores.txt","a+")
score = f.write(username+","+password+","+points+"\n") #It is giving a type error about this line and I cant seem to understand why
f.close()
The error shown is:
line 193, in english
score = (username+","+password+","+points+"\n")
TypeError: must be str, not int
Please let me know if you have a better way of writing the scores into a text file. THank you.

Replace the error line with: score = f.write(username+","+password+","+str(points)+"\n")
