Python

Python is a programming language known for being unusually readable and quick to write. That friendliness made it the default choice for data work and machine learning, so almost all modern AI, from research code to the tools that run models, is written in or driven by Python.

You do not need to know Python to use AI, but it explains why it shows up so often in AI coverage. When an article mentions running a model, fine-tuning one, or an AI agent writing code, Python is very often the language involved.
