python/cpython has 1,628,875 source lines of code out of 2,170,713 total lines across 4,127 files, counted from the c39a32983728f2398bb506c20e5c162d61805da3 ref at commit c39a32983728 by the OctoCounts tokei engine on 2026-09-17. The report is cached by commit, tokei version, and analysis options, so recounting the same revision returns exactly these numbers.

OctoCounts produced this report by resolving python/cpython to commit c39a32983728, 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.
