Where to watch logs?

Question

Python

Let's say in a python file there are several sql queries combined into a transaction. Let's say something went wrong and the script didn't work. At the same time, nothing was displayed in the console to help determine the essence of the error.
Please tell me how to look for information about the causes of the error in such cases?
First, I looked at the postgres logs here: /var/log/postgresql
I don't understand where to look for python logs. What other methods can be tried to determine the cause of the error?

Answer 1

in general, python does not write logs - it just sends it to stderr, and redirecting this stream to a log or simply utilizing it is on the conscience of the developers.
