Provides functionalities for creating and transforming ULIDs (Universally Unique Lexicographically Sortable Identifiers). Utilises a Cython-based implementation for optimal performance, with a fallback to pure Python if Cython is unavailable.

Tuxblocs helps students in K-12 schools to understand the positional numeration system.

SINGULAR is a Computer Algebra System (CAS) for polynomial computations with emphasis on the special needs of commutative algebra, algebraic geometry, and singularity theory.

Provides tools to implement the Secure Remote Password (SRP) protocol for secure password-based authentication and key exchange in Python. SRP is a password-authenticated key agreement protocol (PAKE) that enhances security by allowing for secure password-based authentication and key exchange.

Extension to Python's type annotation system, leveraging the capabilities of typing.Annotated to incorporate metadata and constraints directly into type hints. This package facilitates the representation of common constraints such as value bounds (e.g., greater than, less than), length restrictions on collections, and predicates for runtime checks, among others. Designed to enhance the expressiveness and utility of type annotations for both static analysis tools and runtime validation libraries.

Dunamai is a Python library and command line tool for producing dynamic, standards-compliant version strings, derived from tags in your version control system. This facilitates uniquely identifying nightly or per-commit builds in continuous integration and releasing new versions of your software simply by creating a tag.
