A few typos, grammar mistakes, and code snippet errors in the docs

Documentation

(UPDATE: Added multiple suspected errors in code snippets in the documentation and another typo to this initial report in https://github.com/python/cpython/issues/156233#issuecomment-5435277380 as I was OK'd to open a PR but encouraged to expand the scope before sending a fix.)

Hello Python team,

this is just a typo so I know an issue is not required, but I hope you won't mind if I open one in case someone else wants to include it in a larger typo cleanup PR they are already doing (if no one picks it up after some time and I don't find other typos, I can send a PR).

In the latest version of https://docs.python.org/3/howto/mro.html#python-2-3-mro (archived as is at https://web.archive.org/web/20260822145356/https://docs.python.org/3/howto/mro.html#python-2-3-mro )

• In the sentence

  Then repeat the operation until all the class are removed or it is impossible to find good heads.

  it seems "all the class" should be "all the classes".

Thanks so much!
