Python by the numbers. Rankings, growth, community size, and the scale of Python's dominance.
Python reached #1 on the TIOBE Index in October 2021 and has held the position since. It won "TIOBE Language of the Year" in 2007, 2010, 2018, 2020, 2021, and 2023 — more than any other language.
Source: TIOBE Index, approximate 2024 values. Python has been #1 since October 2021.
The Python Package Index has grown exponentially. The ecosystem doubled in size between 2019 and 2023, driven by AI/ML, data science, and web development demand.
Python is the most-asked-about language on Stack Overflow. It consistently ranks as the #1 or #2 "most wanted" language in the annual Developer Survey. On GitHub, Python is the second most-used language by number of repositories.
| Project | Category | What it does |

Python's statistics tell a story of compounding network effects. More developers means more libraries. More libraries means more use cases. More use cases means more developers. This flywheel has been spinning since the early 2010s and accelerated dramatically with the AI boom starting in 2016.
Python's dominance is not about being the best language for any single task. C is faster. Rust is safer. JavaScript has the browser. But Python is good enough at everything and the best at connecting things together. It is the universal glue language — and in a world of increasing complexity, glue is what holds everything together.
