[ ] It only works with newer Python versions 2. [x] It provides 10-100x faster dependency resolution and automatic virtual environment management 3. [ ] It requires less disk space 4. [ ] It only works with Jupyter notebooks # Why is pyproject.toml preferred over requirements.txt in modern Python projects? 1. [ ] It's shorter and easier to write 2. [x] It follows PEP standards and provides comprehensive project configuration including dependencies, metadata, and build settings 3. [ ] It automatically installs Python 4. [ ] It's only required for web applications # What is the primary purpose of WSL2 for Windows users in data science development? 1. [ ] It makes Python run faster 2. [ ] It's required for all Python installations 3. [x] It provides a native Linux environment ensuring compatibility with data science tools and deployment environments 4. [ ] It automatically installs all required packages # Why should you register a Jupyter kernel when using uv environments in VS Code? 1. [x] VS Code looks for kernels in system-wide locations, but uv kernels are installed locally in .venv/ directories 2. [ ] It's required by uv for all Python projects 3. [ ] It improves notebook performance significantly 4. [ ] It automatically installs missing packages # What is the main benefit of collaborative Git workflows with branching? 1. [ ] It makes repositories smaller 2. [ ] It eliminates the need for commit messages 3. [x] It enables parallel development, reduces conflicts, and provides controlled integration through code review 4. [ ] It automatically backs up all files # Why do merge conflicts occur in Git collaboration? 1. [ ] Git is not designed for multiple users 2. [x] Two people modify the same lines in the same file simultaneously 3. [ ] The repository is too large 4. [ ] One person doesn't have proper permissions # What is the purpose of a GitLab merge request? 1. [ ] To delete branches automatically 2. [ ] To backup project files 3. [x] To enable code review, discussion, and quality control before integrating changes 4. [ ] To merge all branches at once # Which Git configuration is essential before starting any collaborative work? 1. [ ] Setting up SSH keys only 2. [x] Configuring user.name and user.email with your identity 3. [ ] Installing the latest Git version 4. [ ] Creating a .gitignore file # What should you do if your Git push is rejected with "Updates were rejected"? 1. [ ] Force push to override the remote changes 2. [ ] Delete the repository and start over 3. [x] Pull the remote changes first, resolve any conflicts, then push again 4. [ ] Switch to a different branch immediately # What is the recommended approach for dependency groups in pyproject.toml? 1. [ ] Put all dependencies in the main dependencies list 2. [x] Organize dependencies into logical groups (dev, ml, viz) for different use cases 3. [ ] Use separate pyproject.toml files for each dependency type 4. [ ] Only use optional dependencies # What does the `uv sync` command accomplish? 1. [ ] It synchronizes with remote Git repositories 2. [ ] It updates all Python versions 3. [x] It creates a virtual environment and installs all dependencies specified in pyproject.toml and uv.lock 4. [ ] It syncs files between different computers # Why should data files typically be excluded from Git repositories? 1. [ ] Git cannot handle binary files 2. [x] Data files are often large, may contain sensitive information, and can significantly slow down repository operations 3. [ ] Data files change too frequently 4. [ ] It's only necessary for small projects # Which practice best demonstrates professional Git workflow for data science projects? 1. [ ] Making one large commit at the end of the project 2. [ ] Committing only final results without intermediate steps 3. [x] Making incremental commits after major analysis milestones with descriptive messages 4. [ ] Avoiding branches and working only on main
