mypy question
Hi all, I am not sure why mypy thinks this gmPG2.py:554: error: Argument "queries" to "run_rw_queries" has incompatible type "List[Dict[str, str]]"; expected "List[Dict[str, Union[str, List[Any], Dict[str, Any" [arg-type] rows, idx = run_rw_queries(link_obj = conn, queries = queries, return_data = True) ^~~ should be flagged. The intent is for "queries" to be a list of dicts with keys of str and values of str OR list of anything OR dict with keys of str and values of anything I'd have thunk list[dict[str,str]] matches that ? This is on Python 3.11.2 with mypy 1.0.1 on Debian. Karsten -- GPG 40BE 5B0E C98E 1713 AFA6 5BC0 3BEA AC80 7D4F C89B -- https://mail.python.org/mailman/listinfo/python-list

Here is the discussion referred to: https://discuss.python.org/t/what-is-install-paths-to-in-wheel-file/42005 I don't see anything "toxic" in that discussion. You asked questions and people took the time to give clear answers. The basic answer to your question is that PEP 491 was never completed and so there is no accepted specification of the Install-Paths-To feature that it had been intended to introduce. The PEP text itself is reasonably clear about this and also links to the up to date specifications: https://peps.python.org/pep-0491/#pep-deferral Instead for understanding the wheel format the appropriate document is: https://packaging.python.org/en/latest/specifications/binary-distribution-format/ That document does not mention Install-Paths-To because it documents the standards as defined and accepted via the PEP process but PEP 491 was never accepted. -- Oscar -- https://mail.python.org/mailman/listinfo/python-list

Yeah, because you have the God-given RIGHT to be able to say anything you like, on anyone's web site, and nobody's allowed to delete anything you say! That's how it goes, right?

I don't believe in god, and I don't believe he / she can give me rights. What I believe in is that Python is a public good, and its status is enshrined in the license it uses. I also believe that Python Foundation and PyPA are the public bodies that are meant to, beside other things, make sure that the public good stays that way. Me, being a member of the public, for whom the good is mean, means I have a right to discuss, complain or argue about the nature or function of this good. I, or you, or anyone else don't need god to make this happen. The rights I'm talking about are a consequence of the license that governs Python and various satellite projects. > Don't let the door hit you on the way out. Oh, great. Here we go again.

I can't say much for Qt other than there is a GUI designer for it, but I don't know much about it. As to the portion of your question about Python and Tkinter, YES! The project is called PAGE and it is a drag and drop designer using the Tk and ttk toolkits (basically Tkinter).

The current version is 7.6 and you can find it at https://sourceforge.net/projects/page/ and it has been downloaded over 2000 times just in December, and over 26,000 times in 2023.

Both cannot be true at the same time, unless you had some kind of very brief memory loss. > I'm not a lawyer, Neither am I. All I have to work with is my understanding of the English language. Here's how I come to my conclusions. The Python license grants all intellectual rights to Python to PSF (an American NGO, a.k.a. 501(c) organization), which, essentially, can be characterized as an organization for public good. This is what it has to say about itself in its mission statement: > Mission > The mission of the Python Software Foundation is to promote, protect, > and advance the Python programming language, and to support and > facilitate the growth of a diverse and international community of Python > programmers. it also elaborates what it means by "diverse" as follows: > Diversity > The Python Software Foundation and the global Python community > welcome and encourage participation by everyone. Our community > is based on mutual respect, tolerance, and encouragement, and we > are working to help each other live up to these principles. We want > our community to be more diverse: whoever you are, and whatever > your background, we welcome you. My understanding is that "welcome and encourage participation by everyone" is in stark contradiction to banning someone disagreeing with you. Note, I haven't offended anyone. I haven't even spoken to anyone who found themselves being offended. All I did was to describe in some detail the reasons why some projects endorsed by PyPA are a bad idea. You, as well as anyone else, are welcome to believe differently. This is the whole point of diversity allegedly promoted by PSF. I will think you are wrong, but it's not my place to shut you up. Neither is it the place of people in charge of the public discussion of Python or its satellite projects. They are not there to decide who's right and who gets the stage. Their role is to preserve the public good, which any discussion about subjects relevant to Python would be. What happens, however, and this is the unfortunate fate of popular projects, is that a small group of people consolidate all means of control in their hands, and the more control they get, the easier it is to get even more of it. The natural factor that would prevent this from happening: the community dissatisfaction with their role becomes increasingly less powerful as soon as more and more members of the community come to depend on the good provided by the community. If this discuss.python.org is representative of the Python community as a whole, then, unfortunately, it means that the goals PSF set for it are fading into the distance, rather than becoming more attainable. -- https://mail.python.org/mailman/listinfo/python-list

That would then sort of skirt on violation of the Liskov
principle, of which I learned while trying to research this
mypy behaviour.
However, I would not think the above to be a narrowing-down
as it just *selects* one of the explicitely "legal" options.
list[dict[str, str | list | dict[str, Any]]]
should AFAICT expand to:
list[dict[str, dict[str, Any]]]
OR
list[dict[str, list]]
OR
list[dict[str, str]]
the last of which should provide coverage of
[{'some key': 'some value'}]
> Can you use a TypeGuard here?
Not from what I understand about them...

The PyPA are the people who currently maintain the code for various libraries/tools. That is very often not the same as the people who originally wrote the code for the same libraries/tools or for preceding ones. Neither group is the same as the forum moderators (I suspect that there is no intersection between the moderators and the PyPA etc.). > And whenever they had a chance, they'd use it > to pretend that the problems I'm talking about don't exist by deleting > every mention of the problem.

Actually you are wasting the time of others by putting across inaccurate and unhelpful information in a rude way and at the same time criticising others without really understanding who you are criticising and for what. Your contribution is unhelpful mostly (but not exclusively) because of the way that you choose to communicate. I did not realise earlier what you were referring to but I see now that I have email notifications with the content of your posts that were deleted. I am not surprised that they were deleted and that you were banned because if I was a moderator looking at those then I would not expect a promising future for your interactions with others in the forum. There is some significant irony in you describing the forum as a "toxic pit" for deleting your posts. I don't always agree with the moderators and I am not sure that I would have reacted the way that they did but these threads remind me precisely why moderation (including deleting posts such as yours) is needed to *prevent* a forum from turning into a toxic pit. -- Oscar -- https://mail.python.org/mailman/listinfo/python-list

If you'd done a little research, you might have found this: https://peps.python.org/pep-0397/ Yes, it is from the official launcher. I don't see why you'd expect Microsoft to go to the effort of building their own launcher when it can be available for every Python user. > > I don't get all the irrational hate for Microsoft that exists within > > the Linux community. > > Perhaps you are too young to remember when Steve Ballmer was head of > Microsoft? How relevant is this? I remember the days when OS/2 was the big target, and Microsoft was the greatest anti-OS/2 voice out there. Does that affect the way I use tools today? Is it even slightly relevant? I remember when Intel had floating-point division issues in their FPUs. Do I tell people "don't do floating-point math on Intel processors"? Is it relevant?
