Python is a programming language that is simple, versatile, and widely used.
Python is a programming language that lets you work quickly and integrate systems more effectively.
Guido van Rossum's 1991 language optimized for readability, now the lingua franca of AI, data science, scripting and backend web. The 2023 AI boom turned it into the most-used language on GitHub: every major model ships a Python SDK, and PyTorch, pandas and FastAPI anchor its ecosystems. The 2→3 migration pain is long gone
Who it's for
Developers and data scientists who want readable syntax and the richest AI/data ecosystem.
