ValueError: malformed sha256_crypt hash (checksum

Bonjour,

Voila je souhaite crée une simple authentification sur python j'apprend par moi même et je suis encore débutant j'ai rencontré une erreur que je n'arrive pas a comprend ou trouver de solutuions sur internet
Tout aide serait utile!! si vous avez des moyens de faciliter mon code je prend aussi! :)

voila mon code:

from passlib.hash import sha256_crypt
tries = 0

pseudonyme = open("pseudo.txt")
password_file = open("password.txt")
password_file_lines = password_file.readlines()
found = False


def new_hash_password():
    global pass2
    pass2 = sha256_crypt.hash("123")
    new_valid_password()


def new_player_password():
    global tries, pass2
    while True:
        pass1 = input('Please enter a password: ')

        pass2 = input('Now please enter the password again to check: ')

        if pass1 == pass2:
            print('You are now logged in welcome!')
            new_hash_password()
        else:
            print('I am sorry but the password does not match')
            tries += 1
        if tries == 3:
            quit()


def new_valid_password():
    global password
    lines_list = password_file.read()
    password_list = []
    password_list.append(pass2)
    password_list.append(lines_list)
    with open('password.txt', 'w') as filehandle:
        filehandle.writelines("%s\n" % place for place in password_list)
    new_valid_pseudo()


def new_valid_pseudo():
    global pseudo2
    lines_list = open('pseudo.txt').read()
    new_p = pseudo2
    pseudo_list= []
    pseudo_list.append(new_p)
    pseudo_list.append(lines_list)

    with open('pseudo.txt', 'w') as filehandle:
        filehandle.writelines("%s\n" % place for place in pseudo_list)
    print("Hi", pseudo2, ",Welcome on pylilgame!")
    password_file.close()
    pseudonyme.close()
    # connection to server
    quit()


def get_line_number_password():
    global password, i
    password = input("Please enter your password:")
    password = (sha256_crypt.verify(password, password_file_lines[i]))
    lookup = password
    for num, line in enumerate(password_file):
        if lookup in line:
            print(num)


def get_line_number_pseudo():
    global pseudo, i

    with open('pseudo.txt', 'r') as f:
        lines = f.read().split("\n")

    for i, line in enumerate(lines):
        if pseudo in line.split():  # or word in line.split() to search for full words
            print("Word \"{}\" found in line {}".format(pseudo, i + 1))

            get_line_number_password()

def sign_in_password():
    global password,password_check, num
    password = input("Please enter your password:")
    password_check = (sha256_crypt.verify(password))
    if password_check is True:
        print("CC")


def sign_in_profile():
    print("dlapdakfoalfq")


if __name__ == "__main__":

    hello = input("Would you like to sign in or sign up(SI or SU)")

    if hello == "SI":
        pseudo = input("PSEUDO:")
        if pseudo in pseudonyme.read():
            print("The pseudo exists")
            get_line_number_pseudo()
        else:
            print("This pseudonyme doesn't exist!")
    if hello == "SU":
        while True:
            pseudo = input("PSEUDO:")
            if pseudo in pseudonyme.read():

                print("This pseudonyme is already taken!")

            else:
                pseudo2 = input("TYPE YOUR PSEUDO AGAIN:")
                if pseudo2 == pseudo:
                    new_player_password()

                else:
                    print("QUIT")<code python>

et voila l'erreur alors que le pseudo et le mdp sont bien stocké en sha256 dans mon fichier text:

Traceback (most recent call last):

Merci d'avance pour toute aide donné!!!
