Python
Also known as: Python / パイソン
A highly readable general-purpose language that dominates the AI/ML ecosystem. It covers backend development with FastAPI and Django, data analysis, and LLM agent building with equal ease.
Overview
Python's first-class support across LLM frameworks, vector databases, and ML libraries makes it the dominant language for AI agent development. The Anthropic and OpenAI SDKs ship Python as their reference implementation.
Backend Use Cases
FastAPI provides async-first, Pydantic-validated APIs, while Django covers large-scale full-stack applications. For AI agent implementation examples using the Python SDK, see Claude Code Agent SDK guide.
