You Are Going To Like These New Features In Python 3.11

Python 3.11 is here! Not all of the changes are immediately noticeable when you look through the release notes. However, today I will cover 7 new Python 3.11 features that you are going to love because they'll make your life a lot easier.

Buffers on the edge: Python and Rust
One of my least favorite kinds of bug is when two different systems are interacting and the result has bad behavior but it’s difficult to say which (if either!) system is at fault. This is one of those stories, about Python’s buffer protocol and Rust’s memory model.

Migrate PostgreSQL ID’s from serial to identity after upgrading to Django 4.1
In this post, we’ll expand on what this means, why you might want to update existing columns from serial types to identity columns, and a management command to update them.

Allocation Removal in the Toy Optimizer
In the previous post of this series I showed the complete code for writing a toy one-pass optimizer that does constant folding, common subexpression elimination and strength reduction. In this second post, I want to use allocation removal as a more advanced optimization pass. The basic optimization framework is the same, we will use the same datastructures for intermediate representation and also keep using the same union find data structure to store equivalences between IR operations.

Better Python input with Rich

Do you use the "input" builtin to get input from the user? You might want to consider using the input facilities provided by the Rich package instead. This video shows you some of the reasons why Rich is a better option, and some of the features it offers.

Building the Future of TensorFlow
We’ve started planning the future of TensorFlow! In this article, we’d like to share our vision.

Django Performance Improvements - Part 4: Caching in Django Applications
In the first three parts of this series around improving performance in your Django applications, we focused on database, code optimization, and frontend optimization. In part 4, we will focus on ways to improve the speed of the Django applications.

Generating memes and infographics with Pillow
Pillow is used for simple operations on images, like resizing, converting to other file formats, and so on. It also can be used to generate custom graphics like infographics or composites of multiple images - memes, infographics, and more. Let's take a look at how it can be done.

Interesting Projects, Tools and Libraries

JC
CLI tool and python library that converts the output of popular command-line tools, file-types, and common strings to JSON, YAML, or Dictionaries. This allows piping of output to tools like jq and simplifying automation scripts.

DataProfiler
The DataProfiler is a Python library designed to make data analysis, monitoring and sensitive data detection easy.

FlastAPI
A FastAPI-like interface for building APIs in Flask.

File-Inyector
File Inyector is a script that allows you to store any file in an image using steganography.

PyWeb3D
Use the three.js library without writing a single line of JavaScript.

DeepXDE
DeepXDE is a library for scientific machine learning and physics-informed learning.

DictDataBase
A Python NoSQL database that uses dicts, and provided thread and process safety.

cuallee
A data quality acceleration library to get data sets verified in a friendly interface.

EnCodec
State-of-the-art deep learning based audio codec supporting both mono 24 kHz audio and stereo 48 kHz audio.

koda-validate
Typesafe, combinable validation for Python.

New Releases

Python 3.11.0
Python 3.11.0 is the newest major release of the Python programming language, and it contains many new features and optimizations.

scikit-learn 1.1.3
This bugfix release only includes fixes for compatibility with the latest SciPy release >= 1.9.2 and wheels for Python 3.11. Note that support for 32-bit Python on Windows has been dropped in this release. This is due to the fact that SciPy 1.9.2 also dropped the support for that platform. Windows users are advised to install the 64-bit version of Python instead.
