  • typing

    Python static typing home. Contains the source for typing_extensions and the documentation. Also hosts a user help forum.

    See https://github.com/python/typing/issues/256 for a discussion.

  • pydantic

    Data parsing and validation using Python type hints

    Indeed. Currently, Python type hinting cannot exclude types, and, of course, does not enforce anything at runtime anyway - although a library like pydantic can be used to enforce them at runtime (hence its popularity with packages like FastAPI).

  • Scout APM

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.
