What is the best way to start implementing parser logs in python?

Question

Python

I welcome everyone! There is a parser that parses news resources.
The task is:
Implement logs for the parser and write these logs to a separate table in the database.
Question: What is the best way to implement logs for the parser in my code.

The code

The structure of my table for logs in the database:

Answer 1

What is the actual problem?

# В начале работы скрипта
created = time.strftime('%Y-%m-%d %H:%M:%S')
start_time = time.time()

# В конце скрипта
duration = time.time()-start_time # время работы в секундах, дальше конвертируйте как хотите
finished = time.strftime('%Y-%m-%d %H:%M:%S')

You shove these INSERT values ​​into the database.
PS In general, it makes no sense to write such logs in the database, use the logging module instead . It's generally good practice to log scripts.
