Kaisen Yao Mini 4: GitHub Actions Matrix Build for Multiple Python Versions

Project Objective

This project aims to test multiple Python versions and environments using GitHub Actions. The setup-python action is utilized alongside the matrix strategy to run multiple jobs across different configurations, ensuring compatibility and robustness.

The repository includes a Python script main.py with a function double_number(x) that takes a number as input and double it for the output. This functionality is validated through unit tests in test_main.py.

Repository Contents

• main.py: Contains the double_number(x) function.

• test_main.py: Contains test cases for main.py.

• .devcontainer: Configuration for development container.

• ci.yml: GitHub Actions workflow for continuous integration (CI).

• Makefile: Automation for code formatting, linting, and testing.

• requirements.txt: Dependencies for the project.

• README.md: Documentation (this file).

Setup and Workflow

1. Codespaces Setup

   • Open in Codespaces and wait for the container to build.
   • The virtual environment will automatically activate and install dependencies from requirements.txt.

2. Development Workflow

   • Make changes to main.py or test_main.py as necessary.
   • Push changes to GitHub, and GitHub Actions will automatically run the tests in multiple environments and operating systems.

3. Code Formatting and Testing

   • To format code: make format

   • To lint code: make lint

   • Example of lint errors:

     

   • To run tests: make test

   • Example of test cases:
