 - `pyenv` manages multiple Python versions at the system level, allowing you to install and switch between different Python versions for different projects.
 - `direnv` automates the loading of environment variables and can auto-activate virtual environments (.venv) when entering a project directory, making workflows smoother.
 - `.venv` (created via python -m venv or poetry) is Python’s built-in tool for isolating dependencies per project, ensuring that packages don’t interfere with global Python packages.

+Additionally, direnv is used alongside `.envrc` and `.env` files to automatically activate the appropriate virtual environment and load environment-specific variables when entering a folder. 
 
 Each Lambda folder includes its own `.env` file for Lambda-specific settings, while the project root contains a separate `.env` and `.venv` for managing shared tooling, scripts, or infrastructure-related configurations. This setup promotes clear separation of concerns, reproducibility across environments, and simplifies local development, testing, and packaging for deployment.
 
 ## Environment setup
 These dependencies are required for running and debugging the Lambda functions and end-to-end (E2E) tests.

 **Note: While this project uses Python 3.10 (e.g. for Lambdas), the NHSDigital/api-management-utils repository — which orchestrates setup and linting — defaults to Python 3.8.
 The linting command is executed from within that repo but calls the Makefile in this project, so be aware of potential Python version mismatches when running or debugging locally or in the pipeline.**
 2. Run `make lint`. This will:
     - Check the linting of the API specification yaml.
     - Run Flake8 on all Python files in the repository, excluding files inside .venv and .terraform directories.
