Re: on the python paradox
I choose Python and still stick with it as default as I choose Python because of its design beauty. Typing does not mean mandatory braces. There can be an indentation-based language that is strongly typed. Python is beautiful in itself. Beautiful to look at. Source code should be easy for the average human to relate to and connect with easily. Being more alien-ware-like does not magically increase performance. Our taste and quality bar should be high after so much time has passed. I don't see a language as beautiful as it is front-end wise.

Re: Why no list as dict key?
Thanks everybody,
In the the event spam is appended a value, then looking for [1,2] does not
return
anything but looking for [1,2,3] yes. But i gather the way dictionaries are
implemented
makes it difficult to do so ...
Maybe hashes should point to an object rather than being the hash of an
object themselves.
Maybe the speed drop is not worth it.

Re: Best way to check if there is internet?
Normally people put Python in the scripting category. I learnt typed languages like C++ and Java at first. People who learn languages like these tend to put Python in a non-serious category. The post was more ironic than litteral. After 5 years of following the mailing lists i realised that there is more than the eyes meet. My hobby has always been language engineering / compiler theory and just recently i realised that Python is pretty serious about language features. I have been following language feature proposals from various languages. Some decide to avoid Python's route, but others have been trying hard to catch up with Python. One gleaming example is the switch case. JS recently proposed pattern matching, referencing Python and explaining why the proposal is a cool treatment of the usecase. As a side note, if by scripting we mean OS commands, then Python started as a sysadmin language. -- https://mail.python.org/mailman/listinfo/python-list

The upcoming operation is short enough and though we cannot assume that it will be the case when we are running the operation, we sensibly assume it will still be the case.

Re: Best way to check if there is internet?
Well, nice perspective. It's a valid consideration, sound theory but poor practicality according to me. It you view it like this then between the moment we press run or enter key on the terminal, our Python interpreter might get deleted. We never know, it can happen. Though it's nice to go in and catch exceptions, if you have a long operation upcoming it might be nice to see if your key element is present. Much like checking if goal posts are present before starting a football game. You can of course start the match, pass the ball around and when shooting you stop the match as you realise that the goal posts are not around. Checking by exceptions is what the snippet i shared does. But we check for the ability to do it before we start. Of course, it can change in the seconds that follow.

Re: A Newspaper for Python Mailing Lists
Well, this one is a newspaper as opposed to being a newsletter. Newsletters are a collection of links. See AwesomePython PythonWeekly PyCoders Weekly Newspapers also contain articles, the above don't. As some mails pointed out above, this is like the lwn of Python I have been avoiding the topics and formats used by existing newsletters by focusing on news among others. But its funny to see one of them starting to cover news by writing an external article on a website they own then link it in the newsletter. It's what you call competition i guess XD The focus of this one is and remains mailing lists / discuss platforms. A look at the archives and you can see publishing interesting mails. Something you don't have with newsletters. The main aim of it is getting myself updated with discussions and pep status and sharing it with the world. Something i feel i was not getting with existing resources. I had cool tutos/articles, new libs, popular posts, job openings, events but not a complete overview of meta posts.

A Newspaper for Python Mailing Lists
Greetings lists, I have started a newspaper (not newsletter) focused on interesting reads on Python mailing lists. Don't tag on the fact that holiday seasons are the worst times for launch according to marketing folks, I started this to note down interesting mails. This might also be a great way to bring mailing list gems to a wider readership.

print('\N{flag: Mauritius}') not supported in py3.9
Mike Driscoll printed this on Twitter
>>> print('\N{Sauropod}')
秊
Using py3.9 i got the above.
I found the whole CLDR short name here:
https://unicode.org/emoji/charts/full-emoji-list.html
However when i do
>>> print('\N{flag: Mauritius}')
File "", line 1
print('\N{flag: Mauritius}')
^
i get
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in
position 0-18: unknown Unicode character name
So is it that Python3.9 does not support it or what is the issue here?

Re: Getting Directory of Command Line Entry Point For Packages
Greetings, Well since sometimes i have this: https://github.com/shopyo/shopyo Old versions worked as we are using it for FlaskCon <https://github.com/flaskcon/traveller>, even newer versions until sometimes ago. shopyo has a copy of the project which is a flask app in site-packages. upon using shopyo new, it creates a copy of the project in the current folder then on running say shopyo run, it just passes commandline args flask run under the hood Only thing is that os.getcwd is giving the path of site-packages and not the directory from which the command is run from. See the run command's source here: https://github.com/shopyo/shopyo/blob/19dc2ee03ff0a6a0dca3237f80a11478ee2dbe46/shopyo/api/cmd_helper.py#L313 Same goes for other commands.

Re: Why so fast a web framework?
Well, They don't choose languages per se but choose frameworks based on that and ... by virtue of that choose languages. Like just to get faster web services. The benchmark is pretty much referred to in the Python world, web side like https://www.starlette.io/ "Independent TechEmpower benchmarks show Starlette applications running under Uvicorn as one of the fastest Python frameworks available. (*)" https://github.com/tiangolo/fastapi ... (thanks to Starlette and Pydantic). One of the fastest Python frameworks available. Both with links to the benchmarks.

Oh thanks a lot, i was way from list this week Just a note: it's pretty amazing to have at Chris Angelico at your local PUG Else, Well, let's say you have a lib that you need to provide users with a shell for them to try out functions, no need to translate functions to cli args. Like Django provides a shell for users to use. The aim of injection is to allow code usage without imports.

Re: OT: Autism in discussion groups (was: Re: Proposal: Disconnect comp.lang.python from python-list)
Greetings, Out of curiosity, how do people without a Code of Conduct manage and prevent abuse in between people? I was about to organise something last year but did not find a better solution than a code of conduct to ensure smoothness. Well the idea was a before-hand signed code of conduct. It becomes more of an agreement, a pact of good conduct. But i wonder how you handle banning it altogether? Like what happens in the case of abuse. What if you ban and people ask why? How do organisers justify their actions? Even if a code of conduct rings not great with some people, at least it can serve as a hint and guiding principles.

The iso part 2 saute a l'oeil (triggers your sensors, litt. jumps at your eye), spring automatically spells confusions as spring goes in the same direction as timezones I was pointing out to politically related changes whose obviousness and correctness is not gauged from empirical analysis of elements in front of you but requires the further step of knowing what the American people deem as right or wrong not in the sense of morals directly but more of how the country and people live. Let's say the word mouse. A mouse is a mouse, the rodent. But now some bad people take the mouse as their symbol. They put the mouse on their bags, robes, curtains, laptops, pens thereby demonising the mouse. Now mouse lovers are also associated to these people as well as people who care for mouse wellness in laboratories. This happens in Fake Country X. Now some in a country studied English and learnt that a mouse is a four tiny- footed creature with a tail. Being a mouse lover the person decided to name a Python conference PyMouse. Now people start dramatising the situation and label the person as someone not to be collaborated with, someone to be banned from all Py affiliated enterprises. Well that is very bad to begin with. A mouse remains a mouse and the bad folks using the mouse as their symbol exists in majority only in Fake Country X. Someone outside Fake Country X never had the chance to study or imbibe himself with or come across the association of this with that. You presented some cases which are very valid and correct, but i was referring to changes which are not so blatant and obvious. Cases which are wrong for some people but right for others not because of moral correctness directly but more because of associations present in a particular country.

Just a note here, though not in relation to CoC but as someone speaking English far away from a country called America, sometimes i wonder at some changes introduced just because it does not ring well within the country. I agree that the US pushed many many changes used around the world but English is not the property of the people of a specific country. The English community is the sum of people speaking English over the world. Though i am very far from CPython contributions but once changes no longer occur on the basis of technical reasons it raises eyebrows far beyond CPython contributors. Now in the Python community we must verify not only grammatical and structural errors but also US-based nuances in the language. This requires community folks to be in tune with American current affairs and ideological tendencies. This might be a bit too much work as the bridge of union of the community is the Python language, usage and tools. Though English is a core-part of the programming language, this is going too deep. A practical effect of this is that each and every event posters, flyers and websites have to be double checked against US nuances and phrasing. And the PSF must make sure that events sponsored by it or affiliated must follow the same standards. This post is in no way a US-bashing one, or intended to be hurtful in any way. It's an observation that some changes appear totally ok to english speakers until you understand that this and that sounds wrong in a particular country. This poses the question of the legitimacy of the influence of a certain nation over the PSF.

Re: .title() - annoying mistake
Greetings, Missing the 'S renders in my opinion the method unfit to be included in it's current form. It is a call to improve it if possible. We wonder why in the first place such a method exists. If indeed it intends to capitalise all first letters, putting others in lowercase, the ' is a too common case to be ignored. The intent was: "Return a titlecased version of the string where words start with an uppercase character and the remaining characters are lowercase." But the ' is a case acknowledged by the docs: "The algorithm uses a simple language-independent definition of a word as groups of consecutive letters. The definition works in many contexts but it means that apostrophes in contractions and possessives form word boundaries, which may not be the desired result: ... A workaround for apostrophes can be constructed using regular expressions: ..." Why not do it if you know people miss it?

Re: New Python implementation
Greetings list, > Even if Python is my choice language for personal projects, I am not certain it is the right language to use in a classroom context. This sums the view of most teachers in my country. In here for A level at Cambridge for Computer Studies you can choose either Java, or VB or Python The teachers' logic seems to tell them that VB is the simplest of all and more fitted for students. Since we organise the local Python usergroup <https://www.pymug.com>, we have been encouraging the adoption of Python. This happens from experience when teachers think for students, they think student will think like that etc The way schools examinations are set up, learning programming is a bore. Programming requires experimentation and projects. The students must be permitted to explore the wide deep sea that is Python. On one of my projects on Github, i have a toy language, someone from Slovakia (14 years old) built an IDE for it, what was needed was only guidance where he was stuck. The hurdle with Python if any is the setting up and getting the command 'python' to appear in the terminal, which is very easy to get up and running nowadays. When i was in high school, i did not take Computer Studies, but was learning programming on my own, including Python. The irony is that my friends who were learning Python got disgusted with it. Loops and functions turned out to be hard for them. That's because learning for the exam makes you learn the language close to theory. Some commandline stuffs and some numbers stuffs surely is not exiting. Mastery comes with projects, exciting ones. Then whatever the syllabus requires becomes easy. It's a means to an end rather than the end in itself. The teachers' reaction is a reaction to the design of the syllabus. The folks seem to think that let's water it down to a very theoretical approach, strike out practise, strike out the fun out of it and sure the students will find it easier. Since effort is disliked by humans, less effort in learning programming will make students happy. Then, if it was no Python at that time, it might be no Python for life. With that mindset ongoing, those students think they know Python, they studied it, but they missed the whole thing. Forest, trees and leaves. They know only the color of the sign board leading to the place.

Greetings,
Web with Python is really easy to get started with, here
is a simple endpoint with a framework called Flask
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
return 'Hello World’
if __name__ == '__main__':
app.run()
As for Tkinter, it's really annoying.
PyQt5 and others are a lot better.
PyQt5 follows the Cpp function namings

Greetings list, Here is a famous question's solution def cons(a, b): def pair(f): return f(a, b) return pair def car(c): return c(lambda a, b: a) print(cons(1, 2)(lambda a, b: a)) print(car(cons(1, 2))) The aim of car is to return 1 but i don't understand how lambda achieves this Kind Regards, Abdur-Rahmaan Janhangeer https://www.github.com/Abdur-RahmaanJ Mauritius sent from gmail client on Android, that's why the signature is so ugly. -- https://mail.python.org/mailman/listinfo/python-list
Documenting the Python Community
Greetings list, I have a project in mind to help document the Python community. It involves among others keeping a within reach info of user groups (name, location, contact) and checking activity status. Sending the mail to this list since i could not find a <https://www.python.org/psf/committees/> community <https://www.python.org/psf/committees/> workgroup. I know Mr Chris is in the Wiki team and that Mrs McKellar once toured Python usergroup spaces for a PSF community-related initiative many years ago. Besides those i don't know any specific person who might be interested This occurs after we organised <https://flaskcon.com> FlaskCon <https://www.youtube.com/channel/UC3QC5pASs8v5YVxKwJDtZeQ>. It was an ugly experience contacting user groups around the world. The wiki is outdated. Many user groups are no longer active, some websites are down, others have weird ways of communicating. This mail is basically to gather interested folks together with the hope of hatching a minimum viable plan d'action. Being myself a usergroup organiser <https://www.pymug.com>, we'd like to find a way to 1. make user groups compliant to a minimum standard 2. put the appropriate mechanism in place so that the PSF can easily have a watch over user groups and give them some bumps from time to time 3. some kind of onboarding and advices for new user groups In parallel I am also thinking of documenting user groups histories, starting with those I have some sort of relationship with. The idea behind is to reinforce the community touch. The draft might seem a tedious task for the expected benefits but with the right approach it will be smooth. Feel free to continue the conversation!

Re: What might cause my sample program to forget that already imported datetime?
Btw why a datetime in datetime? It causes much confusion. I dont know the design decision behind, if someone knows, it might be good to explain I dont expect it to change anytime soon due to backward compatibility, but just for knowledge.

Re: Faking stdlib
The last time this was raised, it seemed that folks in here don't have a clear idea of what the standard library is ^^ https://mail.python.org/archives/list/python-id...@python.org/thread/XSYEVRPJQUX7VBTPNIJMUFZQIZ7WLOQU/ A summary: https://lwn.net/Articles/794458/ Kind Regards, Abdur-Rahmaan Janhangeer https://www.github.com/Abdur-RahmaanJ Mauritius sent from gmail client on Android, that's why the signature is so ugly. -- https://mail.python.org/mailman/listinfo/python-list
