fanuelal/alx-backend-python ? reverse-engineered prompt

Build me a small Python learning project for backend concepts, split into a few folders for type annotations, async functions, async comprehensions, generators, and unit and integration tests.

I want the code to be simple but correct, with clear docstrings everywhere, proper type hints, and style that passes basic Python linting. The exercises should show things like annotating function inputs and return values, working with async code, using asynchronous comprehensions, writing generators, and testing with unittest. Keep everything compatible with Python 3.7 and make the files runnable like normal school assignments.

If you need to, look up current docs online for typing or async details, but keep the implementation straightforward and focused on learning.
