Python Code Review Prompts: Automated Static Analysis & Refactoring (2026)
Master Python code review prompts for automated PR audits. Learn how to detect type errors, memory leaks, performance bottlenecks, and PEP 8 style flaws.
Automating code review pull-request audits using Python Code Review Prompts ensures incoming code adheres to PEP 8 standards, defensive exception handling, and security best practices before merging into production repositories.

1. Production Python Code Review System Prompt
```xml
1. Check for missing type hints (`mypy` compliance).
2. Identify unhandled exceptions and missing defensive `try...except` blocks.
3. Detect performance bottlenecks (e.g., N+1 database queries, inefficient list comprehensions).
### Audit Summary
- [Severity: High/Med/Low] Line #: Issue description.
### Refactored Code
```python
# Clean PEP 8 refactored implementation
```
```

Frequently Asked Questions
How can Python code review prompts catch type hint errors?
Instruct the LLM to run a virtual Mypy type check on the code, flagging missing return type annotations or implicit `Any` usage.
What safety rules should be included in automated code review prompts?
Require the model to check for SQL injection, unhandled promise/async exceptions, hardcoded credentials, and memory bloat.
Can Python code review prompts generate refactored diffs directly?
Yes! Direct the model to output refactored implementation inside clean markdown code fences alongside an executive audit summary.
