# python/cpython SLOC report

> As of 2026-08-31 (commit 03503dccd0aa), python/cpython contains 2,163,559 total lines: 1,623,307 code, 237,418 comments, 302,834 blank, across 3,999 files in 36 languages (top: C 31.3%). Counted with tokei via OctoCounts.

OctoCounts produced this report by resolving python/cpython to commit 03503dccd0aa, 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.
