Higher Kinded Types in Python Higher kinded types (HKT) are a notion in type theory that can be really helpful in functional programming and typing tensors and matrices. HKTs aren’t supported yet in Python, but you can emulate them. NIKITA SOBOLEV

How Async Should Have Been Sometimes synchronous and asynchronous code can look very similar. The only difference might be the use of async and await keywords. In this opinion piece, Nikita Sobolev argues that the potential for repeated code is a design fault of Python’s asyncio framework, and describes a solution that allows synchronous Python to execute asynchronous code.

Do Not Log What makes a good log? When should you log something, and when is logging overkill? In this opinion piece, Nikita Sobolev argues that logging isn’t always best-practice in an application and discuss some alternatives that might make better sense from a business perspective.

Conditional Coverage Sometimes your code has to take different paths based on the external environment. Make sure that your coverage follows it smoothly. NIKITA SOBOLEV • Shared by sobolevn

Typed Functional Dependency Injection in Python “Dependency injection is a controversial topic. There are known problems, hacks, and even whole methodologies on how to work with DI frameworks. It is not the case when using a functional approach.” SOBOLEVN.ME • Shared by Nikita Sobolev

Testing Django Migrations A web app outage post-mortem with useful tips and tools for testing Django migrations. NIKITA SOBOLEV

Python Code Complexity Waterfall What can be done to prevent your Python code from getting too complex? A good linter setup does much more than finding missing commas and bad quotes. A good linter allows you to rely on it with architecture decisions and help you with the refactoring process. NIKITA SOBOLEV

Testing Mypy Stubs, Plugins, and Types “pytest-mypy-plugins is an absolute must for people who work a lot with types or Mypy plugins in Python. It simplifies the process of refactoring and distributing types.” NIKITA SOBOLEV

Enforcing The Single Responsibility Principle (SRP) in Python The Single Responsibility Principle (or SRP) is an important concept in software development. The main idea of this concept is: all pieces of software must have only a single responsibility. Nikita’s article guides you through the complex process of writing simple code with some hands-on refactoring examples. You’ll use callable classes, SRP, dependency injection, and composition...
