General Guidelines
Choose Python when:
- •You need to develop quickly and iterate fast
- •Working on data analysis, ML, or scientific computing
- •Building web applications or APIs
- •Scripting and automation tasks
- •When developer productivity is more important than raw performance
Choose Rust when:
- •Performance and efficiency are critical
- •Building systems where safety is paramount
- •Working on concurrent or parallel systems
- •When you need predictable performance
- •For long-running applications where stability is key
Consider Using Both
Many successful projects use both Python and Rust together. You can use Python for high-level application logic and Rust for performance-critical components. Tools like PyO3 make it easy to call Rust code from Python.
Example Workflow:
- Prototype in Python for rapid development
- Identify performance bottlenecks
- Rewrite critical paths in Rust
- Expose Rust functions to Python using PyO3
- Get the best of both worlds!
