The Standard or user specifig logging is carried out by the log.py module of the logging package ka_uts_log using the standard- or user-configuration files in the logging package configuration directory:
The Logging configuration of the logging package could be overriden by yaml files with the same names in the application package- or application data-configuration directories:
Logging defines log file path names for the following log message types: .

Python packages Name Definition Python package Python packages are directories that contains the special module __init__.py and other modules, packages files or directories. Python sub-package Python sub-packages are python packages which are contained in another pyhon package.
Python packages Sub-directories Name Definition Python package sub-directory Sub-directories are directories contained in python packages. Special Python package sub-directory Python package sub-directories with a special meaning.
Special python Sub-directories Name Description bin Directory for package scripts. cfg Directory for package configuration files. data Directory for package data files. service Directory for systemd service scripts.
Python package files Name Definition Python package files Files within a python package. Special python package files Package files which are not modules and used as python and used as python marker files like __init__.py. Python package module Files with suffix .py; they could be empty or contain python code; other modules can be imported into a module. Special python package module Modules like __init__.py or main.py with special names and functionality.
Special python package files Name Type Description py.typed Type checking marker file The py.typed file is a marker file used in Python packages to indicate that the package supports type checking. This is a part of the PEP 561 standard, which provides a standardized way to package and distribute type information in Python.
Special Python package modules Name Type Description __init__.py Package directory marker file The dunder (double underscore) module __init__.py is used to execute initialisation code or mark the directory it contains as a package. The Module enforces explicit imports and thus clear namespace use and call them with the dot notation. __main__.py entry point for the package The dunder module __main__.py serves as an entry point for the package. The module is executed when the package is called by the interpreter with the command python -m <package name>. __version__.py Version file The dunder module __version__.py consist of assignment statements used in Versioning.
Python elements Name Description Python method Python functions defined in python modules. Special python method Python functions with special names and functionalities. Python class Classes defined in python modules. Python class method Python methods defined in python classes
Special python methods Name Type Description __init__ class object constructor method The special method __init__ is called when an instance (object) of a class is created; instance attributes can be defined and initalized in the method.
