Bug in Python.
by Prakash Mudholkar 07 Feb '22

07 Feb '22

Hello - I wish to bring to your kind notice a bug in Python. Given any matrix X. While trying to compute the CoVariance matrix of that matrix X, Python does NOT compute the CoVarianceof the given matrix X. Instead, Python comptes the CoVariance of the Transpose of the given matrix X. This appears to be a bug in Python. Please refer to the below website for a given matrix and what the result should be after the computation of it's CoVariance. And I have provided a screenshot of what Python is returning. https://www.itl.nist.gov/div898/handbook/pmc/section5/pmc541.htm Please let me know if you have any questions. Regards, Prakash

Re: <documentation>In section 4.6. Defining Functions, It should be print(a,end==' ') in place of print(a, end=' ') (Ruchi Sharma)

Hi Rushi Sharma, The documentation is correct, it is print(a, end = ‘ ’). The syntax error is from your code. Regards, Lateefah.

<documentation>In section 4.6. Defining Functions, It should be print(a,end==' ') in place of print(a, end=' ')

Hi Team, I am a beginner in python. I was going through the documentation for the first time. This link: https://docs.python.org/3.8/tutorial/controlflow.html In section 4.6. Defining Functions, It should be print(a,end==' '). "==" in place of "=". Please correct it. Let me correct if I am wrong. >>> def fib(n): # write Fibonacci series up to n ... """Print a Fibonacci series up to n.""" ... a, b = 0, 1 ... while a < n: ... print(a, end=' ') ... a, b = b, a+b ... print() ... >>> # Now call the function we just defined: ... fib(2000) Regards, Ruchi Sharma

RFC: New/update the Docs Sphinx theme: responsive, edit page links,
by Wes Turner 23 Sep '21

23 Sep '21

Where would be the best place to discuss or just improve the CPython docs sphinx theme? What would Python need in a {PyData,} Sphinx theme fork: - [ ] ENH: add <edit on github> links to every docs page - [ ] ENH: responsive breakpoints for mobile devices - [ ] ENH: responsive fonts - [ ] ENH: toggle-able dark theme - [ ] ENH: interactive code examples (in WASM with pyodide like JupyterLite) - [ ] ENH?: Two sidebars: {Global TOC} {Content} {Document TOC} The PyData theme [bandwagon, feature justification, maintenance burden justification] Src: https://github.com/pydata/pydata-sphinx-theme Docs: https://pydata-sphinx-theme.readthedocs.io/en/latest/ ```quote Other sites that are using this theme: - Pandas: https://pandas.pydata.org/docs/ - NumPy: https://numpy.org/doc/stable/ - SciPy: https://scipy.github.io/devdocs/ - NetworkX: https://networkx.org/documentation/latest/ - Bokeh: https://docs.bokeh.org/en/latest/ - JupyterHub and Binder: https://docs.mybinder.org/, http://z2jh.jupyter.org/en/latest/, https://repo2docker.readthedocs.io/en/latest/, https://jupyterhub-team-compass.readthedocs.io/en/latest/ - Jupyter Book beta version uses an extension of this theme: https://beta.jupyterbook.org - Fairlearn: https://fairlearn.org/main/about/ ``` The sphinx-book-theme theme (Jupyter Book theme) has a few possibly necessary features for the {CPython, Devguide, *} docs: https://github.com/executablebooks/sphinx-book-theme https://sphinx-book-theme.readthedocs.io/en/latest/ :: ```quote A Sphinx theme with a clean design, support for interactive content, and a modern book-like look and feel. Flexible content layout: Inspired by beautiful online books, such as the Edward Tufte CSS guide Visual classes designed for Jupyter Notebooks: Cell inputs, outputs, and interactive functionality are all supported. Launch buttons for online interactivity: For pages that are built with computational material, connect your site to an online BinderHub for interactive content. Bootstrap 4: To style visual elements and add functionality. International: All text integrated in the theme is translated to the specified Sphinx language. ``` https://github.com/python/cpython/blob/main/Doc/conf.py#L68 : ```python html_theme = 'python_docs_theme' ``` https://github.com/python/cpython/blob/main/Doc/requirements.txt#L12 ``` # The theme used by the documentation is stored separately, so we need # to install that as well. python-docs-theme ``` Pypi: https://pypi.org/project/python-docs-theme/ Src: https://github.com/python/python-docs-theme/ What are some better ways to add {Source RST, Source, Edit, History, and Annotate} links to every sphinx doc page than sphinxcontrib-srclinks? https://github.com/westurner/sphinxcontrib-srclinks#usage - sphinxcontrib-srclinks: Source RST, Source, Edit, History, and Annotate, Clone URL - [ ] copy clone URL to clipboard button - pydata-theme: 'Edit this page' on the document TOC sidebar - sphinx-book-theme: {gh, bb, gl} icon > 'Suggest edit' - [ ] ENH: add collapsible sidebar to whatever is chosen as a suitable replacement for the current non-responsive theme

Typo in contextvars.Token.old_value
by Eric Irrgang 09 Sep '21

09 Sep '21

For https://docs.python.org/3.7/library/contextvars.html#contextvars.contextvar… and newer, an "is" should be "if". Token.old_value says "It points to Token.MISSING is the variable..." instead of "It points to Token.MISSING if the variable..." (Per https://docs.python.org/3/bugs.html#documentation-bugs, I am "short on time") Cheers.

Hi Python Foundation, I'm from Ghana and I chanced on this beautiful pdf from your foundation on the Internet and I want to say thank you. I'm a beginner and I'm glad to have this material. Thank you so much. I want to use python in automation and chemical engineering so it's a great start for me. Thank you. Regards Aaron

Epub version
by trimder＠protonmail.com 05 Sep '21

The epub version of docs is too big and therefore slow to use comfortably with the average e-reader. Maybe it would be better to split up the documentation into separate parts instead of combining it all together.

Python Package documentation error
by Krishna 03 Sep '21

03 Sep '21

Hi Python Team, I think the statement "The __init__.py files are required to make Python treat directories containing the file as packages" is wrong in the documentation[1] because it is valid only for Python 2.x version not Python 3.x version. Even though it is good practice to have this file, it is not mandatory to have in Python 3x. to treat directories as packages. So I think we should correct it. [1] https://docs.python.org/3/tutorial/modules.html?highlight=packages#packages Thanks, Krishna

Inconsistent documentation for `set.issubset` vs `set.isdisjoint`.
by Jose Ville 03 Sep '21

03 Sep '21

Hello, In the set documentation <https://docs.python.org/3.7/library/stdtypes.html#set>, it is mentioned: Note, the non-operator versions of union(), intersection(), difference(), > and symmetric_difference(), issubset(), and issuperset() methods will > accept any iterable as an argument. Through some trial, it seems that `isdisjoint() <https://docs.python.org/3.7/library/stdtypes.html#frozenset.isdisjoint>` also accepts any iterable as an argument; however, there is no mention of this in the documentation. The documentation seems to imply that `isdisjoint()` would only accept a set as an argument: set.disjoing(other) Return True if the set has no elements in common with other. Sets are > disjoint if and only if their intersection is the empty set. Perhaps, `isdisjoint()` should be added to the list of set functions which are documented as accepting any iterable as an argument: Note, the non-operator versions of union(), intersection(), difference(), > and symmetric_difference(),* isdisjioint()*, issubset(), and issuperset() > methods will accept any iterable as an argument. > Best, Jose
