What are good resources for an intermediate programmer to learn more?
Im in between jobs right now and want to try and develop my skills. Should i work on trying to become an expert in specific libraries that are common or learn better habits for optimizing code? What resources would you recommend for someone who is pretty familiar with the core language?

instance folder is automatically created
While trying to create a database with the following code
from app import db
db.create_all()
the database is being created in the automatically created instance sub-dircetory, while in the tutorial I watched it is directly being created in the directory, the programme is running fine but why the difference.
On surfing the web I read that instance folder should not be added to the version control, so should I then not add my database to my GitHub repo.

Run external programs intuitively in Python
Hi all!
It's the creator of [Rocketry](https://github.com/Miksus/rocketry), [Red Mail](https://github.com/Miksus/red-mail) and [Red Box](https://github.com/Miksus/red-box) again. This week I thought to make it easier to integrate command-line programs to your Python applications.
I came up with [Scriptor](https://github.com/Miksus/scriptor):
>>> from scriptor import Program
>>> python = Program("python3")
>>> python('myscript.py', report_date="2022-11-12")
"printed values"
What happened? The above ran the command:
`python3 myscript.py --report_date 2022-11-12`
and it returned whatever the program printed (in standard output aka. stdout).
So Scriptor makes it easy to integrate external programs or scripts written in other languages or in Python but using different Python interpreter.
For example, using Git is quite handy with it:
>>> from scriptor import Program
>>> git = Program('git')
>>> myrepo = git.use(cwd="path/to/myrepo")
>>> myrepo("log", n=2)

Do you test authentication in your views?
I have a view that creates a resource. Using this view is allowed only for authenticated users. In this case, should I be writing a test that checks that only authenticated users are allowed to call this view?

Finally Pushed Myself to do Full DRF + React
I've always been a supporter of Keep it Simple Stupid and leveraging server-side rendering to the max but I've also felt like I needed to build a complete SPA as a side project.
Understand this is 100% in beta stage, but I'm pretty happy with this little thing: pagesauce.io
The premise is to be a better A/B testing app by being simple, fast-to-onboard, and smart. Facebook ads/pixel for any content on your website. Here's a thread explaining the use case a bit better than I am here: https://twitter.com/wolfofwebsites/status/1591459576196513793?s=20&t=Me7tQot\_DpQBSOVzOXxy0w
I've attached quick video demo since I don't have a landing page or anything yet. I think I am gonna send it on Product Hunt in a couple weeks (if I can get some beta testers). I've got an email list for it if you feel so inclined. Or just go ahead and register \- I've got chat on there and would love to hear about all the bugs haha
​
Edit: I also have zero intentions of attempting to charge anyone willing to beta test and mess with this thing. This is the first time I've implemented an embedded script like this and the nerd side of me is so satisfied - I just want

Lightweight Python DB that can hold arbitrary binary objects
I've been fiddling with some file sensor/watchdog type programs lately. I've tried messing around with pickleDB and tinyDB, but I'd really like to be able to find a lightweight database that I can store a binary object in as well. So things like zips, images, pickled python objects (which I thought pickledb would do)
Anyone have any ideas? Someone mentioned RocksDB but it didn't make sense to me, maybe I have to dig more into the documentation there?

Starlite without Starlette
Howdy fellow travellers!
A little less than a month ago I wrote in this subreddit about our plans to drop Starlette as a core dependency of Starlite. After a lot of work, I am glad to say that this effort is now complete: Starlite 1.39.0 was released a few hours ago and Starlite no longer depends on Starlette. You can find the release notes here.
Some of you might wonder why this is news at all? Well for us its a big milestone - Starlite started out as an API framework competing with FastAPI using the same building blocks - Starlette and Pydantic. But Starlite grew and evolved, and it reached a point where it no longer made sense to continue to extend Starlette. The result is that Starlite is now a complete ASGI framework on its own accord, without dependning on any ASGI toolkit.
The name Starlite now carries a bit of history in it - you can see the readme of the library in Github which has a section discussing this.
As always I invite you all to discuss, and we are always looking for more contributors and maintainers!

This is how i got more performance in WebSockets than Node or Bun using Python
Bun is changing out the scenario for Node.js, with much more performance in HTTP and WebSockets, but how FAST it is compared with Python?
In the Bun website https://bun.sh/, the source code of the WebSocket benchmark is available, so... let's try to run Falcon + uvicorn on it!
I just simplified a little the benchmark, to remove a string concatenation, to measure more of the raw throughput with less impact other things, and runned using Falcon + uvicorn and socketify.py, when benchmarking i was talking with Vytautas Liuolia in the Falcon Gitter for tunning HTTP performance in other raw throughtput testing as well, and Falcon is not so much focused on WS performance, this also depends a lot of ASGI server too. For this test i choose uvicorn with gunicorn as ASGI server.
Messages per second with Linux x64:
https://raw.githubusercontent.com/cirospaciari/socketify.py/main/misc/ws-bar-graph.png
Socketify got almost 900k messages/s with PyPy3 and 860k with Python3 the same performance as Bun that also uses uWebSockets, Falcon at 35k messages/s and Falcon with PyPy3 improves into 56k messages/s, node.js manages 192k.
You can see the source code for the benchmark here https://github.com/cirospaciari/socketify.py/tree/main/bench
and if you have some time check out the github https://github.com/cirospaciari/socketify.py this project can be even better with some community

HOW TO ACCESS VARIABLE OUTSIDE LOOP
I have a loop in jinja which displays a collection of items. I included a purchase button in each item whereby clicking it brings up a modal popup where i plan to set up a form to collect some data before posting it to the backend. I'm stuck in trying to get the id of each item since the modal is outside the loop.
I tried using js which i could only be able to display the id in modal using innerHTML. How can I access the id value in jinja?

What Are the Most Common Mistakes That People Are Doing in Learning Python? 5,000+ Learners' Data Analyzed
As some of you may know, my friends and I launched an app called Codehub a month ago, and it already has 5,000+ users. The app offers free Python challenges to practice. We've analyzed the data of all 5,000 users to understand the most common mistakes people make while doing the Python challenges.
Common Error #1: Syntax Errors
Over 2,400 people had syntax errors. These mistakes include omitting a keyword, misspelling variable names, and omitting a symbol such as a colon, comma, or bracket.
Common Error #2: Logical Errors
These errors occur when a program does not crash but produces an incorrect result. Over 14,000 challenges were completed on Codehub in the previous 1.5 months, and 40% had logical errors. These include using integer division instead of floating point division and using wrong variable names.
Common Error #3: Iterating over a list and modifying it
Deleting an item from a list or array while iterating over it is a widespread error, not just in our app's context. While some of these issues may be obvious to the naked eye, others may be difficult to identify and resolve.
If this is interesting, please let me know. I plan to publish an extended article about the most common

I'm working with a small team in a Django project, one of the requirements says that I need to use MSSQL SERVER, but I don't know how to share the database
Hi, I'm working on a university Django project, one of the requirements was to use MSSQL SERVER, but I'm having problems sharing the database.
I was thinking that a solution would be to use SQLite and then migrate back to MSSQL SERVER, but I read that it creates different problems when more than three people work on the same embedded database.
A friend suggested me another solution which is to work on Digital Ocean and use free credit, but I don't know how to work on a host, what should be the methodology with GitHub?
If anyone has a better idea or thinks any of this could work, it would be a great help.
