本指南面向 Python 开发者,介绍如何在 Kiro 中提升 Python 项目的开发效率。内容涵盖 Python 环境准备(虚拟环境最佳实践)、Open VSX 扩展推荐(PyLint、Jupyter、Python Debugger 等)、通过对话搭建 Django/FastAPI/数据科学项目的提示词示例,以及用 steering 文件传递 PEP 8 规范、Django 视图模式和数据科学工作流约定。还介绍了 hooks 自动化(pytest 生成、依赖更新)和通过 #docs 快速引用 Python/PyTorch 文档的技巧。

Kiro 为 Python 项目提供强大的 AI 辅助能力,帮助你更高效地编写、调试和维护代码。

环境准备

开始 Python 开发前,请确认以下依赖已就绪:

  • Python:推荐 Python 3.8 及以上版本,官网下载
  • pip:Python 包管理器,随 Python 一起安装
  • 虚拟环境:使用 venvvirtualenvconda 管理项目依赖
  • Git:版本控制

推荐扩展

Kiro 兼容 Open VSX 扩展市场,以下扩展可提升 Python 开发体验:

扩展说明
PythonIntelliSense、调试、代码补全、重构、单元测试一体化
PyLintPython 代码风格和错误检查
JupyterJupyter Notebook 支持,含 IntelliSense 和调试
Python Debuggerdebugpy 调试器,支持断点和变量检查
Rainbow CSV彩色高亮 CSV/TSV 文件,支持 SQL 风格查询

让 Kiro 帮你搭建开发环境

项目配置与结构

Kiro 可以帮你初始化配置文件、搭建标准项目结构:

"Set up a requirements.txt with development dependencies"
"Configure a .env file for my Django application"
"Set up a Python package structure with proper __init__.py files"
"Create a Flask project structure with blueprints"
"Organize my data science project with notebooks and modules"
"Create a pyproject.toml for a FastAPI project with pytest and black"

代码分析与重构

Kiro 可以检查代码质量、添加类型注解、协助代码重构:

"Analyze this function for potential bugs and performance issues"
"Refactor this code to follow PEP 8 style guidelines"
"Add type hints to this Python module"
"Convert this synchronous code to use async/await"

调试辅助

遇到 Python 报错时,直接把 traceback 发给 Kiro:

"Explain this Python error: AttributeError: 'NoneType' object has no attribute 'split'"
"Help me debug this Django view that's returning a 500 error"
"Why is my pandas DataFrame operation so slow?"

Steering 文件配置

Steering 允许你把项目上下文和规范传递给 Kiro。Kiro 可自动生成三个基础文件:

  1. product.md — 产品目标与核心功能
  2. tech.md — 技术栈与开发规范
  3. structure.md — 项目目录结构说明

创建自定义 steering 文件

  1. 在侧边栏打开 Kiro 视图
  2. 在 "Agent Steering" 区域点击 + 按钮
  3. 输入文件名(描述性标题)
  4. 按 Markdown 格式填写内容

自定义 steering 文件存储在 .kiro/steering/ 目录,Kiro 会在每次交互时自动读取。

Python 通用规范 steering 示例

创建 python-conventions.md

markdown
Python Conventions

Naming Conventions
- Use snake_case for variables and functions
- Use PascalCase for classes
- Use UPPER_SNAKE_CASE for constants
- Use descriptive names that explain purpose

Code Style
- Follow PEP 8 guidelines
- Use Black for code formatting
- Maximum line length of 88 characters
- Use type hints for all public functions

File Structure
- One class per file for large classes
- Group related functions in modules
- Use __init__.py files for package organization
- Separate tests in tests/ directory

Documentation
- Use docstrings for all public functions and classes
- Follow Google or NumPy docstring style
- Include type information in docstrings

Django 专项 steering 示例

创建 django-patterns.md

markdown
Django Development Guidelines

Model Design
- Use descriptive model names
- Add __str__ methods to all models
- Use model managers for complex queries
- Follow Django naming conventions for fields

View Structure
- Prefer class-based views for complex logic
- Use function-based views for simple operations
- Keep business logic in models or services
- Use proper HTTP status codes

Performance Best Practices
- Use select_related and prefetch_related for queries
- Implement database indexing for frequently queried fields
- Use caching for expensive operations
- Profile database queries in development

数据科学项目 steering 示例

创建 data-science-patterns.md

markdown
Data Science Development Guidelines

Notebook Organization
- Use clear section headers and markdown cells
- Keep notebooks focused on single analyses
- Export reusable code to Python modules

Data Handling
- Validate data quality early in pipelines
- Use consistent column naming conventions
- Handle missing values explicitly

Model Development
- Use cross-validation for model evaluation
- Document model assumptions and limitations
- Implement proper train/validation/test splits

Agent Hooks 自动化

Kiro 的 agent hooks 可以自动化常见 Python 开发任务:

自动生成测试

保存 Python 文件时自动生成 pytest 测试:

"Create a hook that generates pytest tests when I save a new Python module"

自动更新依赖

检查并提示过期的 pip 包:

"Create a hook that checks for outdated pip packages and suggests updates"

代码风格检查

When a Python file is saved:
1. Run flake8 or pylint on the file
2. Report any style or quality issues
3. Suggest fixes for common problems
4. Update docstrings if missing

虚拟环境检查

When requirements.txt or pyproject.toml is modified:
1. Check if virtual environment is activated
2. Install or update dependencies automatically
3. Report any dependency conflicts
4. Update requirements-dev.txt if needed

内置文档引用(#docs)

Kiro 提供 #docs 快捷指令,可在对话中直接引用官方文档:

"#Python How do I use context managers effectively?"
"#Pytorch how can I add a custom operator?"
"#PySide6 What is the best way to add a button?"

也可以直接引用特定文档 URL:

"#URL https://docs.python.org/3/library/asyncio.html"

快捷调试方式

操作快捷键说明
Inline ChatCmd/Ctrl + I针对当前代码提问或请求修复
Add to ChatCmd/Ctrl + L将整个文件加入对话,进行全文分析
Quick Fix悬停错误 → Quick fix → Ask Kiro自动把报错代码加入对话并开始调试

常见问题

Q:Kiro 能帮我自动创建虚拟环境吗?

可以。在对话中告诉 Kiro 你使用 venv 还是 conda,它会给出对应的创建和激活命令。通过配置 hooks,还可以在 requirements.txt 变动时自动触发依赖安装。

Q:steering 文件中应该写 Black 格式化配置吗?

不建议。代码格式化最好交给 Black + pre-commit hook 自动处理,steering 文件应聚焦于 Kiro 无法自动感知的内容:架构决策、业务规则、团队约定。

Q:数据科学项目和普通 Python 项目的 steering 文件有什么区别?

数据科学 steering 文件更强调数据处理规范(缺失值处理、列命名约定)、实验可复现性要求,以及 Notebook 和模块代码的职责划分。可以在通用 python-conventions.md 的基础上叠加一个 data-science-patterns.md
