[issue28798] Describe character as a string of length one instead of size one in tutorial
New submission from Liang-Bo Wang:
In Tutorial "An Informal Introduction" section, character is introduced as a
string of size one. It may be true for python 2.x, where str can be interpreted
as bytes. However in Python 3, strings are unicode thus the size and the length
of a string are usually not the same. Also, using size of a string can be
confused with the result returned by sys.getsizeof(mystr), where
sys.getsizeof('a') != 1.
Therefore using "a string of length one" to describe a character may be less
confusing. The patch attached changes the wording.

[issue26246] Code output toggle button uses removed jQuery method
Liang-Bo Wang added the comment:
Thanks for the merge.
I pulled the change and checked the result, but I found the patch missing a
line to initiate the correct display state when the button was created. That
is, it forgot to set `button.data('hidden', 'false');` when adding the button.
This causes the first click on the button to have no effect. But the following
clicks will work.
I filed the new patch to add this line back. I'm so sorry I missed this line :(

[issue26246] Code output toggle button uses removed jQuery method
New submission from Liang Bo Wang: The code output toggle button (the `>>>` button on the top right) has been disappeared and not functional on the current online documentation (both 3.4+ and 2.7). For example, see any doc page that has interpreter outputs: https://docs.python.org/3/tutorial/introduction.html#numbers https://docs.python.org/3.5/tutorial/introduction.html#numbers https://docs.python.org/3.4/tutorial/introduction.html#numbers https://docs.python.org/2/tutorial/introduction.html#numbers These toggle buttons are created dynamically using jQuery by the script at Doc/tools/static/copybutton.js. However, the method .toggle() it used for click event handling has been deprecated since jQuery 1.8 and removed since jQuery 1.9. https://api.jquery.com/toggle-event/ Current Python documentation ships with jQuery v1.11.1 and it has a new .toggle() method with totally different behavior, which controls animation and hide the element. Therefore those buttons are invisible and has no effect. https://api.jquery.com/toggle/ To achieve the old behavior, one now needs to create this toggle event on one's own. The most popular way to store the toggle state is by jQuery's .data() data storage. A patch is attached to make the button functional again. -- assignee: docs@python components: Documentation files: copybutton_js.patch keywords: patch messages: 259279 nosy: Liang Bo Wang, docs@python, eric.araujo, ezio.melotti, georg.brandl priority: normal severity: normal status: open title: Code output toggle button uses removed jQuery method type: behavior versions: Python 2.7, Python 3.4, Python 3.5, Python 3.6 Added file: http://bugs.python.org/file41764/copybutton_js.patch ___ Python tracker <http://bugs.python.org/issue26246> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
