Files with trailing whitespace cannot be pushed to the git cpython repository. For 3.x (on Windows), help.html is generated, after editing idle.rst on the master branch, with sphinx-build -bhtml . build/html python_d.exe -c "from idlelib.help import copy_strip; copy_strip()" Check build/html/library/idle.html, the help.html diff, and the text displayed by Help => IDLE Help. Add a blurb and create a PR. It can be worthwhile to occasionally generate help.html without touching idle.rst. Changes to the master version and to the doc build system may result in changes that should not changed the displayed text, but might break HelpParser. As long as master and maintenance versions of idle.rst remain the same, help.html can be backported. The internal Python version number is not displayed. If maintenance idle.rst diverges from the master version, then instead of backporting help.html from master, repeat the procedure above to generate a maintenance version.
