What are some of the best python talks to (re)watch?

Recently i have been looking around for cool/good talks about python and found some things that i thought were super interesting like

https://www.youtube.com/watch?v=YY7yJHo0M5I

https://www.youtube.com/watch?v=sPiWg5jSoZI

but most of these are already a bit older.

Do any of you have interesting talks you can recommend?

Adding Virtual Environments to Git Repo

At work, the engineer in charge of writing python automation tests includes venvs (both linux and windows) in the git repo. His reasoning is that people will have to download the specific python version we are using to the write code anyways; this way when we select the interpreter (which should already be symlinked to the default global python interpreter) all the packages we use will already be available (and auto-updated if necessary when rebasing).


This rubs me the wrong way, I still assume the best and most pythonic way of working is to create your own local environment and installing the packages using a requirements.txt file, possibly adding a git hook to automatically call pip install every time you rebase.

What do you guys think?

Made a Free Proxy Rotator library

Hello there,
I made a free proxy rotator library that scrapes and validates proxies from freely available sources and rotates them. Integrates well with requests library. Should be helpful for web scraping. Check it out at https://github.com/sachin-sankar/swiftshadow.

Monitor flask app for HTTP status codes and access

What are some open sources tools available to monitor my flask app?

Goal is to monitor access, HTTP status codes, etc.

Better if it can be integrated with Grafana or some observability tools out there.

How can we use the MVC pattern in flask?

I am interested in improving my programming in flask and I would appreciate some advice about how to conform to a model-view-controller (MVC) pattern in flask. I am unclear about which of the MVC components map to those that we commonly see in flask (views/routes, models, templates, etc.) and could use some feedback.

I was thinking of creating:

routes.py: where the `@bp.route` decorated functions go
controllers.py: functions that get called by the decorated route functions and bring together the views.py and models.py functionality to return a view to the front-end
views.py: for returning JSON representations and rendering HTML templates ready to hand back to the front end
models.py: for managing database models.

The following is an example - it isn't from a real app and probably won't work as it is. I am just using it to illustrate my thinking:

routes.py:

@peoplebp.route('/api/people')
def getpeople():
return controllers.getpeople()

controllers.py:

def getpeople():
people = models.Person.query.all()
return views.renderpeople(people)

views.py:

def renderpeople(people):
people = p.name for p in people

Flask-Session not working with 2.3 removing sessioncookiename

Like the title says sessioncookiename was removed from 2.3 and Flask-Session uses that, Flask-Session hasn't seen any updates in years so I don't think their gonna fix it on their end. I've seen a fork of it called flask-session2 but don't really know if it's trustworthy. Any ideas?

from flask import Flask
from flaskrestful import Api, Resource

app = Flask(name)
api = Api(app)

class HelloWorld(Resource):
def get(self):
data={"data":"Hello World"}
return data

api.addresource(HelloWorld,'/hello')

Use AWS Elasticache Redis as Celery Broker?

So we're using AWS to deploy our project, and using Celery for Event Driven Architecture, so celery workers are always up and running.

We wanted to use Redis as a broker, since SQS has no monitoring support from either Celery or Celery Flower. We tried using AWS MemoryDB Redis as broker, but were unsuccessful as Celery at the moment does not support clustered Redis architecture. So now we're using Elasticache Redis as the broker, but the AWS docs says that Elasticache is not persistent, and data loss might occur if the primary node fails, which means that some messages might be lost which would be really hard to recover.

So my question is that is Elasticache is a wise choice for using Redis as a broker, or we should look at something else?

Also, if someone here has used Elasticache Redis as their celery broker, please let me know your experience and if you would recommend it.

Rendering child templates with context

I am using class based views and my problem is that I have a base template for cards, which provides the styling and functionality for them. I also have multiple card view classes (Card1, Card2, etc) which each have context, and set the template_name to the base template for the cards. I want to be able to call each card class inside my home template, instead of using {% include BaseCardTemplate with..... %} because there is a lot of context. Is there a standard Django way to do this?

​

And if there is a standard way to do this in Django is it also applicable including templates that rely on models? For example if I have a button that when clicked, I want to display a window that gets its information from the app's model using the button's data attribute as the primary key, how is this done?

Is there a way to integrate djdt results with tests?

The problem is djdt is not suitable to be active during tests because it significantly slows down the tests and is unnecessary. But this means that before committing, manual work has to be done to check for query efficiency which is a waste of time and is the whole purpose of tests. I'm thinking it would be nice if there's a way to set a maximum number of duplicate queries/any other metrics, for each view and have it checked by a test. It still would be inconvenient to enable djdt over the entire suite just to enable running just a few tests. How do you usually approach this? I'm using pytest + django test client + selenium fyi.

Learning more about forward and reverse relationships.

Hello there, I am relatively new to django and came to know about forward and reverse relationships and wanted to craft a real world problem. Let's say I have the following classes

class User(AbstractBaseUser):
phone_number=models.CharField()

class ClientPackage(models.Model):
user = models.OnetoOneField(User,,related_name='user_client_package')
package = models.ForeignKey(Package,null=True, blank=True)
expiry_date = models.DateField()

class NotificationSettings(models.Model):
user = models.OneToOneField(User, related_name="user_notification_settings")
master = models.BooleanField(default=True, help_text='set false turn off notifications.')

Now to get all the user\_id and phone\_number of currently active users who have set the master control for notifications to be true I can do it in three ways

1. User.objects.filter(
user_client_package__pacakge__isnull=False,
user_client_package__expiry_date=date.today(),
user_notification_settings__master=True
).values_list('id', 'phone_number')

2. ClientPackage.objects.filter(
