🦄Articles & Tutorials
Django and Next.js are very powerful web frameworks for backend and frontend development. This tutorial builds a restaurant menu management project using Django 4.2 and Next.js 13.
This tutorial for a full-stack project is more comprehensive than the previous one. In addition to implementing CRUD operations, it also covers dashboards, form filtering, Tailwind CSS, working with different databases, and building the backend with Node.js and Django, respectively.
Numba is a popular solution to speed up Python code. The author open-sourced a library called Profila that is specifically designed to analyze the performance of Numba code itself. The article introduces how to use it and also discusses three limitations of performance analysis.
The author analyzes 10 pitfalls of the datetime module and introduces the situation of mainstream third-party libraries (such as arrow, pendulum, DateType, heliclockter), and finds that most of them have the same problems. What is a better date and time library? The author open-sourced a library that attempts to solve the problems in the article.
Here, "grammar" refers to writing grammar, not programming grammar. The article introduces four libraries, language-tool-python, Gramformer, Ginger, and pyaspeller, for checking and automatically correcting grammatical errors.
This is the transcript of a talk the author gave at PyCon Sweden 2023, sharing his debugging mindset, tools, and techniques, including tools like snoop, pdb/ipdb, PuDB, web-pdb, birdseye, Kolo, and more.
Debugging is hard, and debugging across multiple languages is even harder. This article introduces how to debug a mixed language issue, using GDB to debug Python+C, locating and fixing a deadlock issue, and sharing some debugging experiences.
This article is an analysis and interpretation of Guido's 2008 article Sorting a million 32-bit integers in 2MB of RAM using Python. The solution uses the less common modules struct, array, and heapq, as well as techniques such as context managers and generators.
This tutorial shows how to define an AST with Pylasu, generate a parser using ANTLR, implement a transformation from the ANTLR parse tree to the Pylasu AST, and finally build a toy programming language parser with a CLI.
What is dynamic programming? What are its features and advantages compared to other approaches? This article starts with a common programming problem and gradually introduces caching, optimizing the cache, and dynamic programming, unveiling the mystery of dynamic programming.
Python supports type hints, but it's not mandatory. In fact, there are many cases where it's not recommended to use type hints. This document from the typing module lists some reasons why you might want to avoid using type hints.
How to run large language models on your personal laptop? This tutorial provides a complete walkthrough of running llama.cpp on different operating systems, including selecting and downloading the model, setting prompts, formatting LLM outputs using GBNF grammars, streaming responses, multimodal models, and more.
🎁 Python Trending Weekly 🎁 organizes its content into seasons, with every 30 issues forming a season. The highlights from the first season have been compiled for your convenience. You can access them online here (Chinese).
🐿️Projects & Resources
This popular project has nearly 3K stars in just one week! The CPU.xlsx file provides a 16-bit CPU, 16 general-purpose registers, 128KB of RAM, and a 128x128 display area. It is compiled using Python. (3K stars)
This datetime library addresses some of the problems that the standard library and other third-party libraries don't solve very well, as mentioned earlier.
It consists of a series of code language models, each of which is a 2T token-trained model with multiple model sizes, advanced code-completion ability, and excellent performance in various benchmarks. (4.3k stars)
Features: Fully async, SQLAlchemy 2.0, Powerful CRUD, Dynamic construction of complex queries, Advanced SQL joins, Offset or cursor-based pagination, Modular and extensible, Autogenerated API.
This framework enables you to effortlessly build AI services with Python code. Its key features include: well-designed abstractions, model startup with just a few lines of code, built-in examples for common models (e.g., Llama, SDXL, Whisper), automatic batch processing, background tasks, and more. (1.9k stars)
Let AI curate, write, design, and edit content based on your personal taste and interests, powered by 6 specialized agents that search the web for the latest content and aggregate well-known news sources.
A lightweight notification library written in pure Python that allows you to send notifications via a plethora of services like Telegram, Discord, Slack, Amazon SNS, Gotify, and many more, supporting various notification formats such as SMS, email, and desktop notifications. (9.7K stars)
A distributed task processing library based on PostgreSQL, providing Django integration and easy to use with ASGI frameworks. It supports features like async, periodic tasks, retries, arbitrary task locks, etc.
It can run multiple instances of netperf/iperf/ping simultaneously and aggregate the results, presenting the data through an interactive GUI and an extensible plotting facility. It supports local and remote hosts and can collect statistics about CPU usage, WiFi, qdisc, and TCP sockets, among other things.
urllib3 has released version 2.2.0, which brings support for use in the Pyodide runtime! The latter is a Python interpreter that runs in the browser and is the technical foundation for frameworks like PyScript and Jupyterlite. This has major implications for Python frontend development, and the future looks bright.
Gnuplot is a powerful, open-source plotting tool for generating various types of 2D and 3D plots. This project integrates it with Numpy, leveraging its data handling and plotting capabilities.
RAG (Retrieval-Augmented Generation) + vector database to build a Chinese history knowledge Q&A application, supporting both "Milvus Scheme" (on-premises) and "Zilliz Cloud Pipelines Scheme" (on cloud), providing a web UI interface based on gradio. The default model is GPT4, and other LLMs can be easily switched.
