/ 09 апреля 2020

Привет, я новичок в курсе python. Я хочу создать форму входа в QT5 Desinger, в которой я разработал форму в QT5 desinger. Я делаю функцию входа в систему, когда при нажатии кнопки появляется сообщение об ошибке, которое я не понимаю, что такое это. Ниже приведены изображения ошибок введите описание изображения здесь

Код моей функции 

def login(self):

        # Establish Connection

        with sqlite3.connect('collage_App.db') as db:
            c = db.cursor()

        # Find user If there is any take proper action

        find_user = 'SELECT * FROM admin WHERE user_name = ? and password = ?'
        c.execute(find_user, [self.uname.Text(), self.upass.Text()])
        result = c.fetchall()
        if result:
            #self.logf.pack_forget()
            #self.head['text'] = self.username.get() + '\n Loged In'
            ms.showerror('Success!', 'User Name And Password Are Correct.')
        else:
            ms.showerror('Oops!', 'User Name And Password Are Wrong.')

код события моей кнопки 

 self.login_button.clicked.connect(self.login)

код всего моего файла 

#!/usr/bin/python
