# Describe Your Python Experience
Describe your practical Python experience, including the kinds of systems or analyses you built, quality practices, and limits of your expertise.
### Constraints & Assumptions
- Use concrete work rather than a list of libraries.
- Distinguish production experience from prototypes or coursework.
- Discuss testing, packaging, typing, performance, or operations where relevant.
### Clarifying Questions to Ask
- Was the code a service, pipeline, automation, or analysis?
- How was correctness tested?
- Where did Python stop being the right tool?
```hint Show the engineering context
A language is credible experience only when the answer explains what was built and how it was maintained.
```
### What a Strong Answer Covers
- Representative Python work and your contribution.
- Testing, dependency, observability, and deployment practices.
- A debugging or performance lesson.
- Honest boundaries and how you choose another tool.
### Follow-up Questions
1. How do you keep a large Python codebase maintainable?
2. Describe a performance problem you would not solve by micro-optimizing Python.
Overview: Present Python experience through maintained production work, correctness practices, operational judgment, and honest tool-selection limits.
