Last reviewed on January 3, 2026
Why This Tool?
Industry-standard tool used by professional developers. Learning it now prepares you for real jobs.
Visual Studio Code is a free, open-source code editor from Microsoft. With Python and Jupyter extensions, it becomes a powerful environment for data science and ML development.
IntelliSense: Smart code completion for Python and other languages; Debugging: Set breakpoints and inspect variables; Git Integration: Built-in version control; Extensions: 30,000+ extensions including Python, Jupyter, Docker; Remote Development: Code on remote servers or containers; Jupyter Support: Run notebooks directly in VS Code
Developers, data scientists who want a professional IDE, anyone building production-ready code, teams needing Git integration
Complete beginners who need immediate results (use Jupyter first), users who only need quick experiments (use Colab)
Best for writing production-ready code, version control with Git, debugging complex programs, building full applications
Steeper learning curve than Jupyter, requires more setup, not ideal for quick experiments or teaching
- Completely free
- Professional-grade IDE
- Excellent Git integration
- Massive extension ecosystem
- Great for production code
- More complex than Jupyter for beginners
- Requires more setup
- Can be overwhelming with too many features
- Heavier than simple editors
Free and open-source
Industry-standard tool used by professional developers. Learning it now prepares you for real jobs.
Install VS Code → Add Python extension → Create .py files → Run code → Use Git for version control → Deploy to production
Beginners use it to write simple Python scripts. Advanced users leverage debugging, Git integration, remote development, and build full applications.
Professional alternative to Jupyter for production code. Integrates with Git, GitHub, Docker, cloud platforms. Used alongside Jupyter for development workflow.
PyCharm (more powerful but paid), Jupyter (better for experiments), Sublime Text (lighter but less features)
