Boštjan Mejak <bostjan.mejak at gmail.com> added the comment: I have also discovered some non-capitalised "python" words in the very same argparse docs. These 2 subtitles have those typos: 1) 15.4.1.1. Creating a parser 2) 15.4.6. Upgrading optparse code Please fix this as well. ---------- _______________________________________ Python tracker <report at bugs.python.org> <http://bugs.python.org/issue11885> _______________________________________
