Ive created the path in urls.py, but how do I get the event-id in views.py? I want to assign that event-id to a variable.

Using Python and AI to query and ask question about your audio data

Hey there!

After receiving such a warm response to my last tutorial on extending OpenAI with new knowledge, allowing you to ask it anything your heart desires, I'm excited to share a brand new video on querying your audio data! Check it out here: **https://youtu.be/Klf9aIxh1Lc**

In this video, I tackle a super common use case that I bet many of you have faced. Give it a watch, and let me know if you've experienced the same issue!

I hope you enjoy it and find it helpful. But before you dive in, please keep in mind that you'll be sending your data to an API, so it's best not to use private or sensitive information.

Here's the link to the Github Repo for your convenience: **https://github.com/grumpyp/chroma-langchain-tutorial/tree/main/whsiper-langchain-chroma**

Happy learning!

Is anyone working on edge computing solutions targeting Python?

Many companies are now rolling out their WebAssembly based or isolated V8 edge computing serverless function solutions.

E.g.

[Supabase](https://supabase.com/blog/edge-runtime-self-hosted-deno-functions) (news in today)
Cloudflare

Most of these solutions target TypeScript/JavaScript developers. I wonder if anyone is working on edge computing solution that would target Python as the developer language? Either through WebAssembly compiled (widely supported today) or some specific Python isolation method.

Wakatime with Jupyter (Not in VSCode)

I can see that in wakatime’s leader boards you can sort by “Jupyter”. But I can’t seem to figure out how Wakatime tracks Jupyter if I use Jupyter on a local server outside of VSCode. Any tips?

Introducing Markdown Code Runner: Automatically execute code blocks in your Markdown files! 🚀

Hey r/Python!

I recently developed a Python package called Markdown Code Runner (markdown-code-runner) that allows you to automatically execute code blocks within a Markdown file, including hidden code blocks, and updates the output in-place. This can be super useful for maintaining Markdown files with embedded code snippets, ensuring that the output displayed is always up-to-date and accurate. It also enables generating content like tables, plots, and other visualizations directly from the code.

GitHub Repository: https://github.com/basnijholt/markdown-code-runner

Key Features:

- Automatically execute code blocks, including hidden code blocks, within a Markdown file
- Allows hidden code blocks to generate content like tables, plots, etc.
- Works with Python and Bash code blocks
- Keeps the output of the code blocks up-to-date
- Easily integrates with GitHub Actions
- No external dependencies and works with Python 3.7+

Why Markdown Code Runner?

When creating Markdown files with code examples, it's essential to keep the output of these code snippets accurate and up-to-date. Manually updating the output can be time-consuming and error-prone, especially when working with large files or multiple collaborators. In addition, there might be cases where hidden code blocks are needed to generate content such as tables, plots, and other visualizations without displaying the code itself in the Markdown file.

markdown-code-runner solves this problem by

New release of FastKafka improves testability

We were searching for something like FastAPI for Kafka-based service we were developing, but couldn’t find anything similar. So we shamelessly made one by reusing beloved paradigms from FastAPI and we shamelessly named it FastKafka. The point was to set the expectations right - you get pretty much what you would expect: function decorators for consumers and producers with type hints specifying Pydantic classes for JSON encoding/decoding, automatic message routing to Kafka brokers and documentation generation.

https://github.com/airtai/fastkafka

The new release adds in-memory Kafka broker that can be used for testing without the need to install Java and start a broker. It allows you to write a simple-to-understand tests such as this one:

from fastkafka.testing import Tester

msg = IrisInputData(
    sepal_length=0.1,
    sepal_width=0.2,
    petal_length=0.3,
    petal_width=0.4,
)

# Start Tester app and create InMemory Kafka broker for testing
async with Tester(kafka_app) as tester:
    # Send IrisInputData message to input_data topic
    await tester.to_input_data(msg)

    # Assert that the kafka_app responded with IrisPrediction in predictions topic
    await tester.awaited_mocks.on_predictions.assert_awaited_with(
        IrisPrediction(species="setosa"), timeout=2
    )

I used Python to make a BizBuySell web scraper to get businesses for sale in a given state. I used aiohttp to fetch requests asynchronously. The code has a rate limiter as well!

Hey friends! Back again with another python web scraping project.

A founder reached out to me to know if it was possible to scrape BizBuySell for businesses for sale in a specific state. They needed the data for business development. I never scraped this site so I was up for a new challenge.

At first I ran into issues with bot blocking. They use Akamai CDN. However, with a bit more research, I managed to get the data. The site was not too difficult compared to others. No dynamic javascript which means no need to use selenium. I only fetched the first 12 pages to keep the demo short. Happy to answer any web scraping questions.

Nested LDAP groups for Flask not working



Hello!

I am currently using flask_appbuilder.security.manager in order to provide LDAP authentication for my Airflow instance(Version 2.5.0) . When doing the AUTH_ROLES_MAPPING
I have noticed that it only works for direct members of the active directory groups I am calling out. Has anyone been able to get this to work for nested groups?

Example:

in my current set up

AUTH_ROLES_MAPPING = {"CN=ADMINACTIVEDIRECTORYGROUP,OU=ResourceAirflow,OU=ResourceGroups,OU=!!sample,DC=sample,DC=sample" : ["admin"]

User A: member of ADMINACTIVEDIRECTORYGROUP
User B: member of ROLEGROUP which is a member of ADMINACTIVEDIRECTORYGROUP

Only User A would be able to login to my airflow instance as Admin since flask is not recognizing nested group membership

I have tried multiple variations of

member:1.2.840.113556.1.4.1941:=

memberof:1.2.840.113556.1.4.1941:=

to no avail.

Thank you for the help or insight if others have gotten nested AD groups working. This would be extremely helpful.

🚀 Introducing GoRules: Open-Source Business Rules Engine

Hi r/Python,

We've recently developed and published an open-source business rules engine in Rust with native bindings for Python and Node.js. We're excited to share a new blog that describes serverless deployment using AWS S3 and Lambda. You can find it here: [https://gorules.io/blog/python-rules-engine-lambda](https://gorules.io/blog/python-rules-engine-lambda).

**What is GoRules?**

[GoRules](https://gorules.io) is a modern, open-source rules engine designed for high performance and scalability. Our mission is to democratise rules engines and drive early adoption. Rules engines are very useful as they allow business users to easily understand and modify core business logic with little help from developers. You can think of us as a modern, less memory-hungry version of [Drools](https://drools.org/) that will be available in many languages and on many platforms. We prioritise:

* High performance: You can execute thousands of decisions in a second
* Ease of use: We are obsessed with making the best experience for business users
* Flexible deployment: GoRules can be deployed on-premise, in serverless environments or embedded in existing service(s)

**Community**

We are very keen on listening to the community for suggestions and any issues you may face. Feel free to open issues and discuss them below if you have found the project to be useful or are excited about it.

Anyone using database-as-s-service with Django?

For my passion projects I have access to some simple SQL servers through friends, this served me allright in the past. However I had to do everything (security, backups, updates) myself.

I'm now working on a more serious project and I rather don't 'mess' with a database. So I looked for a DBAAS, and found PlanetScale to integrate with Django very easily. It allows me to have the database in the same AWS Datacenter as my app, it takes care of backups even branching and (as long as I pay) I get infinite scaling. For now I'm even getting by on their free tier, so whats the catch? Why ware we still running our own SQL?

I wonder: has anyone of you used Planetscale or any other database as a service tools? I view the costs rather pragmatic: I'm doing this project with just 1 friend, and I rather pay for a managed service. As it's cheaper than me hiring someone who actually knows his shit in regards to databases.

Help with storing data from back end to frontend

Hi guys, so basically I've made a web application and have completed most of the back-end. However, I'm now stuck on an element of the web application. I have a page on my web app that users can input information into and the back end does calculations and provides the user a summary based on the input.

I would like this summary to be permanently stored in a 'Reports' page in the web app so users can scroll through their summaries. How would I do this?

Flask-Session prevent session fixation attack

Hi im developing a web application and trying to make it not vulnerable to session fixation attacks (https://owasp.org/www-community/attacks/Session\_fixation) to prevent this i need to clear the session id when an user logins and assign a new one. I expected i would be able to to it using the same session.clear() that is used at logout but it doesnt seem to work when using it to log in.

​

# LOGIN PAGE
@app.route("/myapp/login", methods=['GET', 'POST'])
def login():
if request.method == 'GET':
return rendertemplate("login.html")
if request.method == 'POST':
args = request.form
if auth(args"username", args"password"):
session.clear()
session"user" = {}
session.get("user")"name" = args"username"
