I’ve updated the paragraph to keepmaster for the container relationship
while removingslave, and adjusted the wording to stay within the scope
of this PR. I also fixed thewinfo_parent markup warning.

Please let me know if this looks good now.

@terryjreedy I have commited the suggested changes Please review and suggest if any change required

I think Serhiy's PR addresses this already and in a better way. What has changed between these two PRs? I would also prefer Serhiy's PR as he has deep tkinter knowledge.

Thanks for the clarification. Since Serhiy’s PR already covers this,
I’m happy to defer. Let me know if you’d like me to close this PR or
if you prefer to handle it.

Thank you for starting this. Serhiy went back to the current tk docs for both docstrings and tkinter.rst.
