Appendix

Package Logging

Description

Logging use the module log.py of the logging package ut_log. The module supports two Logging types:

1. Standard Logging (std) or

2. User Logging (usr).

The Logging type can be defined by one of the values ‘std’ or ‘usr’ of the parameter log_type; ‘std’ is the default. The different Logging types are configured by one of the following configuration files:

1. log.std.yml or

2. log.usr.yml

The configuration files can be stored in different configuration directories (ordered by increased priority):

1. <package directory of the log package ut_log>/cfg,

2. <package directory of the application package ui_eviq_srr>/cfg,

3. <application directory of the application eviq>/cfg,

The active configuration file is the configuration file in the directory with the highest priority.

Examples

Site-packages-path = /appl/eviq/.pyenv/versions/3.11.12/lib/python3.11/site-packages Log-package = ut_log Application-package = ui_eviq_srr Application-home-path = /appl/eviq

Examples of log configuration-files

Log Configuration
Type	Directory Type	Directory	File
std	Log package	<Site-packages-path>/<Log-package>/cfg	log.std.yml
	Application package	<Site-packages-path>/<application-package>/cfg
	Application	<application-home-path>/cfg
usr	Log package	<site-packages-path>/ut_log/cfg	log.usr.yml
	Application package	<site-packages-path>/ui_eviq_srr/cfg
	Application	<application-path>/cfg

Log message types

Logging defines log file path names for the following log message types: .

1. debug

2. info

3. warning

4. error

5. critical

Log types and Log directories

Single or multiple Application log directories can be used for each message type:

Log types and directoriesg

Log type	Log directory
long	short	multiple	single
debug	dbqs	dbqs	logs
info	infs	infs	logs
warning	wrns	wrns	logs
error	errs	errs	logs

Python Files

Overview

Python files

Name	Definition
Python modules	Files with suffix .py; they could be empty or contain python code; other modules can be imported into a module.
Python package files	Files within a python package.
Python dunder modules	Python modules which are named with leading and trailing double underscores.
special Python files	Files which are not modules and used as python marker files like py.typed.
special Python modules	Modules like __init__.py or main.py with special names and functionality.

Python Special Files

Python special 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.

Python Special Modules

Python special 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 package entry point point. 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 classes

Overview

Python classes overview

Name	Description
Python class	A class is a container to group related methods and variables together, even if no objects are created. This helps in organizing code logically.
Python static class	A class which contains only @staticmethod or @classmethod methods and no instance-specific attributes or methods.

Name	Description
Python no instance class method	Python function defined in python classes and decorated with @classmethod or @staticmethod. The first parameter conventionally called cls is a reference to the current class.
Python instance class method	Python function defined in python classes; the first parameter conventionally called self is a reference to the current class object.
special Python class method	Python class functions with special names and functionalities.

Python methods examples

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. The method us a single parameter conventionally called self to access the object.
