The lingua franca of AI engineering. By 2026, Python remains the default language for model training, data pipelines, agent orchestration, and ML tooling, with
Python is the substrate of the AI economy: the language of model APIs, training frameworks, agents, and data pipelines. Typed, tested, async-fluent Python is the baseline craft of AI engineering, and AI coding tools have made writing it faster while making reading it the senior skill.
