Codingame: Clash of Code

Posted on Fri, 26 Apr 2019 in Other • Tagged with codingame

In January I wrote that I want to make a big and interesting project with Codingame - develop an ML-based bot for LEGENDS OF CODE & MAGIC. Procrastinating an attempt to do it (again...) I found out that there is something really interesting on Codingame. Clash of Code! It is a tiny coding competition. After playing them for a while I can say they are awesome to relax from daily routine.

Using import foo.bar.baz as fbb

Posted on Mon, 18 Mar 2019 in Python • Tagged with python

There is a wonderful feature in Python import statement to make an alias for an imported object (import foo.bar.baz as fbb). It allows to avoid name conflicts and improve code readability if necessary. And of course, using it you can easily turn your perfect code into a completely unreadable mess. Recently I’ve seen this several times. I’ve met some strange abbreviations and confusing aliases.

Please Do Not Use "else"

Posted on Tue, 29 Jan 2019 in Python • Tagged with python

I don’t like else if there is return-statement in both branches. It is always possible to write code without that unnecessary if appendage. Such code looks more accurate, more clear and it is easier to read. Why so many developers still use this useless else?

Mobile App with Kivy and Python? Mmm… Not now

Posted on Thu, 25 Oct 2018 in Python • Tagged with python, kivy, mobile

There are several GUI frameworks for Python. Most of them are for desktop applications. Kivy is an exception. Using it you can build project for mobile platforms. Unfortunately, it is not production ready. You have to juggle versions of libraries to make it works. So even having a t-shirt that says print("Python is my favorite language") I have to accept that Python is not for mobile development.

Optional or Not in Abstract Classes

Posted on Mon, 27 Aug 2018 in Python • Tagged with python, type hints

Type hints are not mandatory in Python. So you can use them or not. If you decide work with them you’ll face many difficulties annotating functions or variables. This article shows my point of view on one specific case.

Coders Strike Back Post-mortem

Posted on Thu, 12 Jul 2018 in Other • Tagged with python, c++

The latest couple of months I've spent around 40 hours at weekends and in evenings trying to write a bot that is able to finish the track of Coders Strike Back faster than opponents. During this time I'd made quite a lot of mistakes before I got into the Legendary league. This is a post-mortem for that project.

4 Articles about Python Internals

Posted on Thu, 29 Mar 2018 in Python • Tagged with python, python internals, cpython

Maybe, knowing Python internals is not a thing you should know to be a good Python developer. However, if you want to improve your code it becomes more important. If you know it works under the hood, you write a code with less stupid mistakes and architecture issues.
