python/cpython SLOC report
As of 2026-09-07 (commit 09117bc3173b), python/cpython contains 2,166,256 total lines: 1,625,329 code, 237,769 comments, 303,158 blank, across 4,038 files in 36 languages (top: C 31.3%). Counted with tokei via OctoCounts.
OctoCounts produced this report by resolving python/cpython to commit 09117bc3173b, downloading the repository source archive, and counting every source file with tokei, the open-source line counter written in Rust. The table below breaks the count down by programming language into files, total lines, code lines, comment lines, and blank lines, so the figures can be compared across languages and projects. Results are cached by commit, tokei version, and analysis options, so counting the same revision again reproduces exactly these numbers.
