Если вы создаете новые объекты внутри init, то целесообразнее передавать их уже готовыми в качестве аргументов, а для создания объекта использовать фабричный метод. Это отделит бизнес-логику от технической реализации создания объектов.

В этом примере init для создания подключения к базе данных принимает в виде аргументов host и port:

class Query:
    def __init__(self, host, port):
        self._connection = Connection(host, port)

Get name of current function and caller with Python

With the python module inspect, one can inspect (not kidding) the run-time python stack. Among other things, this makes it possible to get the name of the current function or callers. Handy for logging or debugging purposes. A simple script to illustrate:

import inspect
# functions

rodnaxel

# python setup.py build

from cx_Freeze import setup, Executable
import sys
import os
import shutil
import zipfile


__appname__ = "userial-qt5"
