Introduction to Thalesians.Adiutor Library

Rationale

In a rapidly evolving technological landscape, the ability to write efficient, reusable, and cross-domain code has become paramount. The thalesians.adiutor library was designed to address this need by providing a suite of tools and utilities tailored for developers working across diverse domains such as finance, data science, engineering, and academia.

The rationale behind the creation of this library is rooted in eliminating redundancy, enhancing consistency, and promoting best practices in software engineering. thalesians.adiutor aims to bridge the gap between domain-specific functionality and general-purpose utilities, fostering a unified ecosystem that encourages code reuse and extensibility.

The word "adiutor" is Latin for "assistant". Are we being pretentious by picking a Latin word for the library name? Well, first, it is true that quidquid latine dictum sit, altum videtur. But perhaps more importantly, it's pretty difficult to make an "assistant", "utilities collection", "commons", etc., googlable without resorting to such linguistic tricks.

Installation

pip install thalesians.adiutor

Approach

The library adopts a modular, extensible, and performance-oriented approach. Each module within thalesians.adiutor focuses on a specific set of utilities, such as statistical calculations, randomness, batching, and interval manipulation. The design philosophy emphasizes:

1. Simplicity: Intuitive APIs with clear documentation.
2. Modularity: Independent components that can be combined as needed.
3. Performance: Leveraging libraries like NumPy, Pandas, and SciPy to ensure computational efficiency.
4. Reproducibility: Tools like random state management ensure consistency across runs.
5. Cross-domain Usability: Applicability in various fields, from quantitative finance to machine learning.

By adhering to established software engineering principles, thalesians.adiutor ensures that its tools remain robust, reliable, and ready for real-world applications.
