Interactive code examples need the prompt to be stripped, before copy-and-paste. This is explained in https://docs.python.org/3/tutorial/introduction.html

But this page does not tell us about the [>>>] prompt-toggle at top of each interactive code example. This caused a user error, reported in https://mail.python.org/pipermail/python-ideas/2018-August/052869.html.

The [>>>] toggle isn't in the Python 2.7 docs, so nothing to fix there!

The toggle option is only in the HTML version with javascript enabled. It would apply to PDF renderings or CHM files etc.

  + We wouldn't the the proposed text to be visible in PDF renderings or CHM files etc.

Hi folks! I'm interested in contributing to this issue, but I'm unsure about the context.

Can >>>> prompts be toggled on-and-off in the docs? I do not see that option. I read that this is possible in javascript-enabled versions of the site, but isn't that the default? If so, I have JS enabled and I do not see how to toggle them out :) . Maybe that's part of what we need to fix as well.

Thanks for your time!

Hi David! There is a button marked '>>>' in the top right corner of code blocks with Interactive code examples. This toggles between the interaction as it would appear in a terminal and a mode where only the input is listed without the '>>>'.

See for example the second block on https://docs.python.org/3/tutorial/introduction.html

I added a pull request to attempt to fix this issue. It received a label but no review and has gone stale, so I am sending out a ping.
