Encrypt passwords in python

I am recently working on a program using Pyqt5, and building my self a small software.

the software requires username and password to login , and I want to set once the user name and password, save it in a safe way, and to prevent someone who has my code\ access to my computer to be able to login to my software.

what I did so far is to use keyring module to set a password, and to hash it with passlib - which eventully saves my password after doing hash to it. when the user trys to login - the code takes the entered password and compare it to the hash password in keyring files.

So to the questions are:

1. is it a good way to save the user password like this? is it safe?
2. how can i prevent someone with access to my code or my computer to just open the code and look on the password?

here is the password hash script:

from passlib.context import CryptContext
import keyring

# create CryptContext Object
context = CryptContext(
    schemes=["pbkdf2_sha256"],
    default="pbkdf2_sha256",
    pbkdf2_sha256__default_rounds=50000
)


def password_encrypter (password):
    # hash password
    hashed_password = context.hash(password)
    return hashed_password

def password_hiding (password):

    # Gets password from user and encrypt it
    hashed_password = password_encrypter(password)

    # Hides The Password
    keyring.set_password("service_name", "user_name", hashed_password)

    check_if_hashed = context.verify(password, hashed_password)
    password1 = keyring.get_password("service_name", "user_name")
    
    # Just for testing 
    print ("password from user" , password)
    print ("hashed password : " ,hashed_password)
    print("password from keyring: " , password1)
    return password1


def password_validatation (password):
    hidden_password = password_hiding(password)
    check_if_hashed = context.verify(password, hidden_password)
    print(check_if_hashed)
    return check_if_hashed


# Test 
password_validatation("my_password")

I am adding also the login script:

from PyQt5 import QtWidgets
# from mainwindow import Ui_MainWindow
from qtwidgets import PasswordEdit
from .password_generator import password_validatation

class Login(QtWidgets.QDialog):
    def __init__(self, parent=None):
        super(Login, self).__init__(parent)
        self.textName = QtWidgets.QLineEdit(self)
        self.textPass = PasswordEdit()
        self.buttonLogin = QtWidgets.QPushButton('Login', self)
        self.buttonLogin.clicked.connect(self.handleLogin)
        layout = QtWidgets.QVBoxLayout(self)
        layout.addWidget(self.textName)
        layout.addWidget(self.textPass)
        layout.addWidget(self.buttonLogin)

    def handleLogin(self):
        password = password_validatation(self.textPass.text())
        if (self.textName.text() == 'user_name' and
            self.textPass.text() == True):
            self.accept()
        else:
            QtWidgets.QMessageBox.warning(
                self, 'Error', 'Bad user or password!')

class Window(QtWidgets.QMainWindow):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)
        # self.ui = Ui_MainWindow()
        # self.ui.setupUi(self)

def main():
    import sys
    app = QtWidgets.QApplication(sys.argv)
    login = Login()

    if login.exec_() == QtWidgets.QDialog.Accepted:
        window = Window()
        window.show()
        sys.exit(app.exec_())


if __name__ == '__main__':
    main()
