    pipsi

    pipsi

    pip script installer

    pipsi is an older Python command-line tool for installing Python packages that expose global scripts. Its name stands for “pip script installer.” Instead of installing command-line packages into the system Python environment, it places each package into its own isolated virtualenv. It then symlinks the installed scripts into a user-level binary directory, allowing commands to run globally without using sudo. This design helps avoid dependency conflicts between unrelated Python command-line tools. The project is no longer maintained and now points users toward pipx as the actively maintained successor.

    pivottablejs

    pivottablejs

    Drag’n’drop Pivot Tables and Charts for Jupyter/IPython Notebook

    PivotTable.js is a Javascript Pivot Table and Pivot Chart library with drag-drop interactivity, and it can now be used with Jupyter/IPython Notebook via the pivottablejs module. I first built PivotTable.js with a plan to build an in-browser data analysis tool, and got as far as one where you could load up a CSV file in the browser for display. Since then, however, the Jupyter project has gathered steam and now provides a browser-based interface to some of the most powerful data processing libraries in the world, so it makes sense to interface with it.

    pyhard2, control hardware from python

    An object-oriented framework for the development of instrument drivers

    pyhard2 is an object-oriented framework to help in the development of instrument drivers. pyhard2 is proposed as an alternative to LabVIEW. Emphasis is given on serial drivers but the framework can be used with any socket. The source also contains the implementation of a PID controller and a setpoint ramp generator. The instrument drivers may further be incorporated in a GUI, using, e.g. PyQt or PySide. Threading is automatically taken care of. Furthermore, generic GUI (called controllers) are provided and can be extended.

    pysole

    pysole

    pysole is a wrapper for simulating C# console applications.

    Pysole is a graphical console simulation pygame wrapper or in simpler terms, Pysole uses pygame to simulate a text interface, such as Windows powershell or the Linux Console. Initially Pysole was built to emulate .NET Console Applications with their dynamic text and background colouring. However, .NET Console Applications, without the support of mono cannot run on operating systems other then windows. Pysole can run on any os that python and pygame can.

    pytorch-examples

    pytorch-examples

    Simple examples to introduce PyTorch

    The pytorch-examples project is a collection of concise and practical examples demonstrating how to use PyTorch for machine learning and deep learning tasks. It focuses on clarity and minimalism, providing small, self-contained scripts that illustrate key concepts such as neural network training, optimization, and data handling. The examples cover a range of topics including supervised learning, generative models, and reinforcement learning, making it a valuable resource for both beginners and experienced practitioners. By emphasizing readable code, the repository helps users understand how PyTorch’s imperative programming style enables flexible model development. It also serves as a quick reference for common patterns and techniques used in deep learning workflows. The project aligns with PyTorch’s philosophy of combining usability with performance and flexibility. Overall, pytorch-examples is an essential learning resource for anyone working with PyTorch.

    quantitative

    quantitative

    Quantized transactions python3

    The “quantitative” repository by Jack-Cherish is a tutorial-style codebase for quantitative trading written in Python — essentially a learning resource that guides users through building algorithmic trading strategies step by step. It’s organized as a sequence of lessons (lesson1, lesson2, etc.), making it approachable for learners who want to understand both theory and practice in quantitative finance. The repo is evidently tied to a popular video series (on Bilibili) that reportedly drew substantial attention, suggesting the material is meant to be both educational and hands-on. The README and associated lessons walk the user through implementing algorithms, likely covering data handling, backtesting, and maybe simple trading logic. As an open-source educational resource, it’s designed for Python users interested in automatic trading, algorithmic strategies, and financial data analysis.

    rich

    rich

    Rich is a Python library for rich text and beautiful formatting

    The Rich API makes it easy to add color and style to terminal output. Rich can also render pretty tables, progress bars, markdown, syntax highlighted source code, tracebacks, and more, out of the box. Rich is a Python library for rich text and beautiful formatting in the terminal. Rich works with Linux, OSX, and Windows. True color/emoji works with new Windows Terminal, classic terminal is limited to 16 colors. Rich requires Python 3.7 or later. Effortlessly add rich output to your application, you can import the rich print method, which has the same signature as the builtin Python function. Rich can be installed in the Python REPL, so that any data structures will be pretty printed and highlighted. As you might expect, this will print "Hello World!" to the terminal. Note that unlike the builtin print function, Rich will word-wrap your text to fit within the terminal width.
