2)py 檔放入如下資料

1. from dotenv import load_dotenv, find_dotenv,dotenv_values
   
2. config = dotenv_values(".env")
   
3. load_dotenv(find_dotenv())

5. username = os.getenv("MYSQL_USERNAME").lstrip()
   
6. password = os.getenv("MYSQL_PASSWORD").lstrip()
   
7. database = os.getenv("MYSQL_DBNAME").lstrip()

複製代碼
