Question

我正在使用 sqlalchemy 将数据帧上传到 AWS RDS Mysql。下面是我的代码，我也想显示警告（特别是数据截断）。

def load_data(translog,input_size):

    try:
        print("Creating connection")

        engine = create_engine("mysql+mysqlconnector://<username>:<pwd>@XXXXXXX.rds.amazonaws.com/XXXX",
                      poolclass=NullPool)

        with engine.connect() as connection:
            translog.to_sql(con=connection,name='transtry',if_exists='append', index=False)
            connection.close()

    except Exception as e:
      #except mysql.connector.Error as error:
        print("Failed to insert record into Transaction table {}".format(e))

    engine.dispose()
    print("MySQL connection is closed")

Answer 1

您可以使用python logger模块，它是内置的并将其设置为stdout输出。

参考：https://docs.python.org/3/howto/logging.html
