Can't agree more. Worst release of #python

#python 3.8 is released. The worst python release so far. :=

I hope, that python4 will concentrate on removing useless stuff from the core, performance, and extending typing support.

Ideally, asyncio should be moved to a separate package, := should be undone. We all make mistakes.

​​In a chord diagram (or radial network), entities are arranged radially as segments with their relationships visualised by arcs that connect them. The size of the segments illustrates the numerical proportions, whilst the size of the arc illustrates the significance of the relationships1.

Chord diagrams are useful when trying to convey relationships between different entities, and they can be beautiful and eye-catching.

​​Mypy stubs, i.e., type information, for numpy, pandas and matplotlib for your #ds #python projects.

Lots of functions are already typed, but a lot is still missing (numpy and pandas are huge libraries).

P.S. We are happy to promote any national online activities, which are valuable and open to public.

​​Voila turns Jupyter notebooks into standalone web applications.

Unlike the usual HTML converted notebooks, each user connecting to the Voila tornado application gets a dedicated Jupyter kernel which can execute the callbacks to changes in Jupyter interactive widgets.

- By default, Voila disallows execute requests from the front-end, preventing execution of arbitrary code.
- By default, Voila runs with the strip_source option, which strips out the input cells from the rendered notebook.

​​A terminal-based presentation tool with colors and effects.

Present your stuff without leaving your terminal!

Personal opinion: this might be a really cool thing for live-coding sessions for people using vim/emacs. The context switch would be minimal.

Diagrams lets you draw the cloud system architecture in Python code. It was born for prototyping a new system architecture design without any design tools. You can also describe or visualize the existing system architecture as well. Diagrams currently supports main major providers including: AWS, Azure, GCP, Kubernetes, Alibaba Cloud, Oracle Cloud etc... It also supports On-Premise nodes, SaaS and major Programming frameworks and languages.

#python, #release

> How to make CPython faster.

> We want to speed up CPython by a factor of 5 over the next four releases.
> See the plan for how this can be done.
> Making CPython faster by this amount will require funding. Relying on the goodwill and spare time of the core developers is not sufficient.

This includes JIT and other awesome features for #python

​​Higher Kinded Types in #python!

I am happy to announce that the first version of Higher Kinded Types
emulation is released with full mypy support as a part of
dry-python/returns@0.15.

Try it: https://gist.github.com/sobolevn/7f8ffd885aec70e55dd47928a1fb3e61

In the nearest future, we will share some practical libraries using HKTs in Python, including type-safe business-validation, smart and simple framework-agnostic REST framework, and so on! This is a big day for Python and its ecosystem.

In this article I am going to show how HKT works and why it is useful.

Testing Python Applications with Pytest.

Pytest is a testing framework and test runner for Python. In this guide we will have a look at the most useful and common configuration and usage, including several pytest plugins and external libraries. Although Python comes with a unittest module in the standard library and there are other Python test frameworks like nose2 or Ward, pytest remains my favourite. The beauty of using simple functions instead of class hierarchies, one simple assert instead of many different assert functions, built-in parametrized testing, a nice system of fixtures and the number of available plugins makes it a pleasure to use.

Today mimesis has been designated as a critical project on PyPI.

It's ain't much, but I feel warm when I think about how many people use think I built.

Thank you everyone!

P.S If you don't know what the hell mimesis is, then go and check it out. Maybe you'll find it useful for you.
