My takes from EuroPython 2023 in Prague Wednesday, 19th July, 2023 Kindnesses & Promises Personal experience of a community organiser Petr Viktorin. It felt a bit out of scope for me because Petr spoke about his path through life (we all have some) and emphasized the importance of community in Python. Community is not the most important thing for me in Python - the actual engineering part of Python is. From the members of the Python community (people who know each other and meet often at meetup) it seems that it is a necessity or essential progress, but I think that a lot of people can be part of Python, contribute to it and not be part of this community....

I’ve attended amazing conference Pycon SK in Bratislava 2018. Part of the programme was a contest in a game snakepit (contests info). It was a nice game where contestants should write a behaviour of snake from the old game we all remember from childhood. Instead of paying attention to the conference talks the contest has absorbed me and I created quick and dirty idea of how should snake play the game....

In this article I would like to describe few tools I’m using everyday to be efficient Python programmer. There is multiple approaches how efficiently control your programming environment but I have converged to this set of tools. I’m looking from any tool that I’m using at work to be easy to learn i.e. having shortcuts always somewhere visible. controlable by shortcut that can be carved in my muscle memory. capable of fast perfomance tasks I’m doing quite often....

As some of Python community here in Czech Republic know there was held programming contest called Wood Coding Challenge organized by Wood & Company. The task was to create stock exchange using Python / C / C++ that runs on TCP sockets communicate by JSON messages and presents solid engineering abilities. You can find whole description of task at the website of the contest. This certainly had my attention and during two months I completed this challenge....

We often face an issue that our long running services need some parts to be reloadable without restart of such service. To achieve this I implemented simple abstract class that wraps any container we could use. You can find whole example at my Github page. from abc import ABC, abstractmethod import time class Reloadable(ABC): """ This class wraps a container and expose all its methods. It reloads its content after `reload_every_secs` from `path`....

Recently we faced an issue how to fairly distribute computational resources for our imaging service using Celery. The imaging service does some basic operations with image like resize. We chose Celery to distribute work among our workers. The service works with chunks of 1000 images that is processed in batch. We wanted to avoid situation where one large client uses all processors on a worker and other smaller clients would have to wait....

I gladly present you my most recent piece of work in Python: Pypete - python performance tests. It is plugin to well known nosetests testing framework. If you run nosetests with my plugin turned on, it will timeit every test you have selected. You can save your results to file, compare it with older results and much more. As usual you can find my code at https://github.com/Artimi/pypete and install using pip....
