In the field of Python development in 2025, numerous ultra-modern tools shine like brilliant stars, bringing unprecedented efficiency and convenience to developers.
Code Checking and Optimization: Ruff
Ruff is an ultra-fast Python code checker that significantly enhances code quality and development efficiency with its speed and ease of use. Developers can customize checking rules through a simple configuration file (such as <span>ruff.toml</span>), for example, setting the types of errors to check (<span>select = ["E", "F", "B"]</span>) and ignoring specific errors (<span>ignore = ["E501"]</span>). Code checking can be performed using the command line with <span>ruff check .</span>, and <span>ruff fix .</span> can automatically fix some issues. It helps developers quickly identify potential problems in the code, making it more standardized and reliable.
Web Framework: FastAPI
FastAPI is a modern web framework that leverages the asynchronous features of Python 3.7+, offering outstanding performance. Its usage is simple and intuitive; for instance, to create an interface that handles POST requests, one only needs to define a Pydantic model for data validation and then write an asynchronous function to handle the request and return results. FastAPI also supports automatic generation of interactive API documentation, making it convenient for developers to test and debug. It is suitable for building high-performance web applications and API services, allowing developers to quickly set up powerful backend systems.
Data Processing: Polars
Polars is an ultra-fast data processing library that excels in handling large datasets. It supports reading data from various file formats, such as CSV and Parquet, and provides a rich set of data processing methods. For example, one can use the <span>lazy()</span> method to convert data processing operations into a deferred execution query plan, and then perform grouping and aggregation operations using methods like <span>groupby()</span> and <span>agg()</span>, finally using the <span>collect()</span> method to obtain results. The high performance of Polars makes it widely applicable in the field of data analysis and processing.
Project Management: Poetry
Poetry is a modern Python project management tool that simplifies dependency management and the build process. Developers can create new projects with simple commands (like <span>poetry new my-project</span>) and add dependencies using <span>poetry add</span>. Poetry automatically handles version conflicts of dependencies and generates a <span>pyproject.toml</span> file to manage project configuration information. It also supports virtual environment management, ensuring that the project’s dependency environment is independent and stable.
Terminal Beautification: Rich
Rich is a terminal beautification tool that provides developers with more intuitive and aesthetically pleasing debugging and display tools. It can output rich colored text and beautiful formatting in the terminal, and supports creating attractive tables, progress bars, etc. For example, using Rich, one can easily create a table containing tasks and statuses, displaying it in the terminal to make debugging information clearer and more readable.
Version Management: uv
uv is an efficient Python version management tool that allows users to easily install, switch, and manage multiple Python versions. Whether it’s an old version or the latest version, uv can quickly respond and download the required version. It also supports integration with existing virtual environment tools, providing a more flexible development environment management solution.
Debugging Tools: PyCharm and pdb++
PyCharm is a powerful Python IDE that offers a rich set of debugging tools, allowing users to set breakpoints, step through code, and monitor variables. pdb++ is an enhanced version of the standard pdb, providing richer features and a user-friendly interface. After installation via <span>pip install pdbpp</span>, it can be used more conveniently.
These ultra-modern Python tools provide comprehensive support for developers, covering code checking, web development, data processing, project management, terminal beautification, version management, and debugging. They not only improve development efficiency but also help developers write better code, making them indispensable tools for Python developers in 2025.
