    def connectDb(self):
        try:

            if not self.isConnected():
                self.db = mysql.connector.connect(
                            host = self.host, 
                            user = self.user, 
                            password = self.password, 
                            database = self.database)

            print(self.db)
        except Error as e:
            print(e)
        
    def isConnected(self):
        if self.db is not None:
            return self.db.is_connected()
        else:
            return False

if __name__ == "__main__": 
    db = DatabaseHelper()
    db.connectDb()
