Я задал предыдущий вопрос с тем же названием, но ни одно из предложений не сработало.Я думал, что дополнительный вопрос с перебором всех опробованных путей мог бы дать более ясный вопрос, чем попытка вставить его в исходный пост (но сохранить все отзывы из оригинала: Сложность подключения Python3 к MariaDB - дубль 1) - пожалуйста, дайте мне знать (вежливо), если есть альтернативный предпочтительный подход
У меня Python2.7 и python3 установлены в OpenSuse (Leap 15.1), и у меня установлена MariaDB
uname -a Linux TRANQUILITY 4.12.14-lp151.28.13-default #1 SMP Wed Aug 7 07:20:16 UTC 2019 (0c09ad2) x86_64 x86_64 x86_64 GNU/Linux

Моя программа предназначена для анализа папки, полной файлов CSV, проверки, является ли файл CSV, а затем, если это так, проверка в таблице БД, анализировался ли этот файл ранее.Сценарий python (разрешения: 754) и все файлы csv (разрешения: 644) находятся в одной папке.
К сожалению, он не будет подключаться к БД из сценария!
Использование точно таких же учетных данных и с тем же путем (т. Е. Папка со сценарием csvs & py):
- Из консоли bashЯ могу легко подключиться к БД
me@server:/project/dataCSVs> mysql -u root -p
Enter password: <myPW>

- Из моего скрипта Python, используя

Концентрируясь на драйвере pymysql и python3, функция и соответствующие дополнительные биты в моем коде, который пытается подключиться:
