This guide is designed to +help new students understand how to structure data analysis projects in Python +effectively. By following these best practices, you'll create projects that are +organized, maintainable, and reproducible. + +## Table of Contents + +1. [Project Structure](#project-structure) + - [Separating Data and Code](#separating-data-and-code) + - [Separating Figures and Code](#separating-figures-and-code) +2.

[Additional Resources](#additional-resources) +5. [Conclusion](#conclusion) + +--- + +## Project Structure + +A well-organized project structure is crucial for collaboration and +scalability. Here's a recommended directory layout: + +``` +project-name/ +├── data/ +│ ├── model_weights/ # Trained model weights +│ ├── raw/ # Original, unmodified datasets +│ └── processed/ # Cleaned or transformed data +├── code/ +│ └── my_python_program.py # Python scripts +├── figures/ +├── docs/ +│ ├── my_fancy_latex_thesis/ # LaTeX files for thesis (advised) +│ ├── my_presentation.pptx # Presentation slides +│ └── my_thesis.docx # Word document (not recommended) +├── .gitignore # Files and directories for Git to ignore +├── README.md # Project overview and instructions +└── requirements.txt # Python dependencies +``` + +### Separating Data and Code + +- **Data Directory (`data/`)**: Store all your datasets here. + - `raw/`: Original, unmodified datasets. + - `processed/`: Data that's been cleaned or transformed. +- **Source Code Directory (`code/`)**: Contains all the code scripts and modules. + +**Benefits:** + +- **Organization**: Keeps your data separate from code, making it easier to manage. +- **Reproducibility**: Clear separation ensures that data processing steps are documented and repeatable. +- **Collaboration**: We/you/collaborators can easily find and understand different components of the project. + +### Separating Figures and Code + +- **Figures Directory (`figures/`)**: Store all generated plots, images, and visualizations. + +**Benefits:** + +- **Clarity**: Separates output from code, reducing clutter. +- **Version Control**: Easier to track changes in code without large binary files like images. +- **Presentation**: Simplifies the process of creating reports or presentations by having all figures in one place. + +--- + +## Version Control with Git + +Git is a powerful version control system that helps you track changes, +collaborate with others, and manage your project's history. But what is version +control? Have you ever found yourself creating files like `project_final_v2.py` +or `project_final_final.py`? Version control solves this problem by keeping +track of changes and allowing you to revert to previous versions. +As a bonus, you'll also have a backup of your project in case something goes wrong. + +### Basic Git Commands + +- **Initialize a Repository** + + ```bash + git init + ``` + +- **Add Remote Repository (GitHub, Gittea)** + + ```bash + git remote add origin + ``` + +- **Clone a Repository** + + ```bash + git clone + ``` + +- **Check Status** + + ```bash + git status + ``` + +- **Add Changes** + + ```bash + git add + # Or add all changes + git add . + ``` + +- **Commit Changes** + + ```bash + git commit -m "Commit message" + ``` + +- **Push to Remote Repository** + + ```bash + git push origin main + ``` + +- **Pull from Remote Repository** + + ```bash + git pull origin main + ``` + #### Advanced Git Commands + +- **Create a New Branch** + + ```bash + git branch + ``` + +- **Switch Branches** + + ```bash + git checkout + ``` + +- **Merge Branches** + + ```bash + git merge + ``` + +- **View Commit History** + + ```bash + git log + ``` + +**Tips:** + +- **Commit Often**: Regular commits make it easier to track changes. +- **Meaningful Messages**: Use descriptive commit messages for better understanding. +- **Use `.gitignore`**: Exclude files and directories that shouldn't be tracked (e.g., large data files, virtual environments). + +--- + +## Best Practices for Data Analysis Projects + +1. **Use Virtual Environments** + + - Utilize `venv`, `conda` or `pyenv` to manage project-specific dependencies. + - Document dependencies in `requirements.txt` or use `poetry` for package management. + +2. **Document Your Work** + + - Maintain a clear and informative `README.md`. + - Use docstrings and comments in your code. + - Keep a changelog for significant updates. + +3. **Write Modular Code** + + - Break code into functions and classes. + - Reuse code to avoid duplication. + +4. **Follow Coding Standards** + + - Adhere to PEP 8 guidelines for Python code. + - Use linters like `flake8` or formatters like `black` or `ruff` to maintain code quality. + +5. **Automate Data Processing** + + - Write scripts to automate data cleaning and preprocessing. + - Ensure scripts can be run end-to-end to reproduce results. + +6. **Test Your Code** + + - Implement unit tests using frameworks like `unittest` or `pytest`. + - Keep tests in the `tests/` directory. + +7. **Handle Data Carefully** + + - Do not commit data to version control. + +8. **Version Your Data and Models** + + - Save model versions with timestamps or unique identifiers. + +9. **Backup Regularly** + + - Push changes to a remote repository frequently. + - Consider additional backups for critical data. + +10. **Collaborate Effectively** + + - Use branches for new features or experiments. + - Merge changes with pull requests and code reviews. + +--- + +## Additional Resources + +- **Git Documentation**: [git-scm.com/docs](https://git-scm.com/docs) +- **PEP 8 Style Guide**: [python.org/dev/peps/pep-0008](https://www.python.org/dev/peps/pep-0008/) +- **Python Virtual Environments**: + - [`venv` Module](https://docs.python.org/3/library/venv.html) + - [Anaconda Distribution](https://www.anaconda.com/products/distribution) + - [`pyenv` Virtual Environments](https://github.com/pyenv/pyenv) + +--- + +## Conclusion + +Structuring your data analysis projects effectively is the first step towards +successful and reproducible research. By separating data, code, and figures, +using version control, and following best practices, you set a strong +foundation for your work and collaboration with others. + +Happy coding!
