Async programming in Python uses async/await syntax with type hints to define coroutines and their return types. Type hints clarify function signatures, making async code more maintainable and enabling better IDE support and error detection before runtime.

Pytest tests should use fixtures for setup and teardown, organize tests by module or feature, and follow naming conventions (test_*.py files, test_* functions). This structure improves readability, reusability, and makes tests easier to discover and run.

Code quality improves through consistent docstrings documenting purpose and parameters, proper import organization, and adherence to formatting standards. These practices make code more readable, maintainable, and easier for others to understand and extend.

Yes, type hints work seamlessly with async functions and pytest. Combine async/await with type annotations in function signatures, then write pytest fixtures and tests that handle async code, ensuring type safety across your testing suite.

Modern Python development requires Python 3.7+, pyproject.toml for dependency management, and pytest installed. This setup enables async support, type checking, and organized test execution without external tool dependencies.
