Python: Fixes displaying of error message to properly show the exception details

[victorgarciaaprea]

Motivation and Context

This change is required to properly print exception details when logging an error message, which helps debugging.

Description

Fixes printing of debugging information used here where the exception details were ignored due to the usage of bad syntax.
