Is Python About to Overtake C? Inside the June 2021 TIOBE Top 20 Rankings
The June 2021 TIOBE index shows Python narrowing the gap to C for the top spot, outlines shifts among the top‑20 languages, highlights logo updates, and provides detailed rankings and trends for the top 50 and the remaining languages, offering developers insight into language popularity.
According to the TIOBE Programming Community Index released in June 2021, Python is closing in on C for the number‑one position, with only a 0.7% difference. TIOBE CEO Paul Jansen noted the upcoming 20th anniversary of the index, which has only seen C and Java reach the top spot in the past two decades.
Other notable languages such as Dart, Kotlin, Julia, Rust, TypeScript and Elixir showed no significant changes last month.
The index also introduced attractive logos for each language, now visible across the Top 20 list.

The TIOBE index measures language popularity based on the number of engineers, courses, and third‑party vendors worldwide, using major search engines such as Google, Bing, Yahoo, Wikipedia, Amazon, YouTube and Baidu. Detailed calculation methods are available on the official TIOBE website.
It is important to note that the index does not reflect language quality; developers can use it to assess whether to update their skills or choose a language for new projects.
