Please document sqlite3 return values
by Bjartur Thorlacius 24 May '19

24 May '19

Dear Python 3 documentation team. The documentation for Python 3.7.3rc1 and 3.6.8 describes the sqlite3.Cursor.fetchone as follows: |fetchone|()¶ <https://docs.python.org/3/library/sqlite3.html#sqlite3.Cursor.fetchone> Fetches the next row of a query result set, returning a single sequence, or None when no more data is available. However, when I use the Python 3.7 from the public Docker image 2afe3d389ba0, fetchone seems to return (0,) when no row matches the query. Confusingly, fetchmany and fetchall are only documented as returnig "a list". A more specific type declaration or description of the hierarchical return type would be appreciated. Best regards, Bjartur Thorlacius

[issue37019] Create symlinks relative to cwd
by Serhiy Storchaka 24 May '19

24 May '19

Serhiy Storchaka <storchaka+cpython(a)gmail.com> added the comment: Yes, the current behavior is by design. It is consistent with the os.symlink(), the "ln -s" command, and with any other way of creating symbolic links in other programming languages. ---------- resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue37019> _______________________________________

[issue37019] Create symlinks relative to cwd
by SilentGhost 24 May '19

24 May '19

SilentGhost <ghost.adh(a)runbox.com> added the comment: Shannon, what you're suggesting is prone to the same issue (creating a broken symlink) if a given destination does not exist relative to cwd. I think your current solution is better as it explicitly provides the paths, but it's not generalised enough to warrant a change in behaviour. If you have anything new to add or would like to add a PR, just post on that issue. As you note, the core developer stated that the current behaviour is by design. ---------- _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue37019> _______________________________________

[issue37019] Create symlinks relative to cwd
by Shannon 24 May '19

24 May '19

Shannon <shannonjkeough(a)googlemail.com> added the comment: I can see how this change would be backward incompatible, however the current behaviour seems inconsistent with the way pathlib functions otherwise. Within two lines of code, the same path object can be pointing to two completely different locations simply because it's being used as the src argument to create a symlimk. That's counter to my understanding of the whole point of pathlib. With regard to relative_to, I've found this issue, which doesn't seem to have been touched since 2016. https://bugs.python.org/issue20012 I'm new here, what's the best way to bump an issue? ---------- _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue37019> _______________________________________

Hi just to report last lines results seems to obtain some extra numbers. it may be a bug >>> v[0:5]=6,7,8,9,0 >>> v [6, 7, 8, 9, 0] >>> v[-1]=6,7 >>> v [6, 7, 8, 9, (6, 7)] >>> v[-1:-5]=6,7,9,0,5 >>> v [6, 7, 8, 9, 6, 7, 9, 0, 5, (6, 7)] >>> v[-5:-1]=6,7,9,0,5 >>> v [6, 7, 8, 9, 6, 6, 7, 9, 0, 5, (6, 7)] >>> if it is not disregard this message Saludos cordiales, Jorge Minguet

SilentGhost <ghost.adh(a)runbox.com> added the comment: This would be backward incompatible change. I just wanted to point out that the symlink was only broken because the file did not exist, and one might want to legitimately create a link relative to the target's location. I'd imagine creating a link in the same directory is one such example. I think the issue you're raising can be addressed in documentation, by making clear that the relative link will be relative to target. This is already done in the given example for symlink_to, but could be improved using a target in subdirectory and a clarifying note. The relative_to issue does indeed deserve a separate issue (if there isn't one already). ---------- assignee: -> docs@python components: +Documentation nosy: +SilentGhost, docs@python, serhiy.storchaka title: using pathlib objects to create symlinks produces broken links -> Create symlinks relative to cwd versions: +Python 3.8 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue37019> _______________________________________

Turtle 24.5.1. Introduction
by Iris Lapinski 23 May '19

23 May '19

Dear Python community, I would like to flag a documentation bug to you in https://docs.python.org/2/library/turtle.html It says right now: "Turtle graphics is a popular way for introducing programming to kids. It was part of the original Logo programming language developed by Wally Feurzig and Seymour Papert in 1966." The Wikipedia entry says this: "Logo is an educational programming language, designed in 1967 by Wally Feurzeig, Seymour Papert, and Cynthia Solomon. " I can see three mistakes: - Wally Feuerzeig is misspelled - the year is wrong - Cynthia Solomon is not credited Can you please correct this?

ntuple forward reference
by Finch, Alex 22 May '19

22 May '19

In the Python Tutorial, the term "tuple" is used a number of times long before it is defined. It is defined at 5.3. It is mentioned in 5.1.3 , and 4.7.2 among others. In one case there is a forward reference to where it is defined, but not all. This is rather confusing as tuple is not a common term. Alex -- [cid:part1.717B75BB.C866C0B6@lancaster.ac.uk]
