Rishika Randev's Mini Project 4 (GH Actions matrix) for IDS706

This repository demonstrates a GitHub Actions workflow which tests a basic Python script across multiple Python versions and Ubuntu versions. In order to accomplish this, a workflow yml file is set up with a GH Actions matrix build.

• A Makefile, which runs required installations, and then formats using Black, lints using Pylint, and tests the code using pytest.

• A requirements.txt file, which lists out some basic DevOps and Data Science packages pinned to specific versions for installation.

• A devcontainer folder.

• Github Actions workflows directory and yml file for CI/CD integration and a matrix build.

• A basic Python script main.py for creating a data visualization and generating descriptive statistics of a seaborn dataset on healthcare spending data across multiple countries and years.

• A testing script which tests the functions of the Python script main.py.

Step 1: Set Up

Add seaborn and any other required packages along with the compatible versions to the requirements.txt.

Create Makefile and devcontainer folder with Dockerfile and json for environmental setup.

Step 2: YML File for GH Actions Matrix

Update your GH Actions workflow yml file to build the code using different Python versions with a matrix build.

Step 3: Create Python Scripts

Create a main.py file with a load_data() function, which loads a seaborn dataset called "healthexp" with the following columns:

• Country (either the US, Japan, Canada, Germany, France, or Great Britain)
• Year (data collected between 1970-2020)
• Healthcare spending per person in USD
• Life expectancy

The main.py file also contains a generate_summary_stats() function to describe the dataset, and a generate_line_graph() function to produce a line graph of healthcare spending specifically in the US between 1970-2020.

A separate test_main.py file is used to test the generate_summary_stats() and generate_line_graph() functions.

Step 4: Validate the CI/CD output

Upon pushing to the repository, the GH Actions workflow is run using different Python versions, and all the steps of the Makefile successfully pass for each version.
