See, for example, https://docs.python.org/fr/3/tutorial/introduction.html. It applies to all interactive code examples.

This is https://bugs.python.org/issue34452, transferred here, as a third party issue. It is related to
PEP 545 - Python Documentation Translations.

Here's what I've found. The purpose of python_docs_theme/static/copybutton.js is

Add a [>>>] button on the top-right corner of code samples to hide the >>> and ... prompts and the output and thus make the code copyable.

To do this it contains code

    var hide_text = 'Hide the prompts and output';
    var show_text = 'Show the prompts and output';

Somehow, this text needs to be internationalised.
