Add StreamBlock child items programmatically in Wagtail

Hello, I have the following setup for a pricing page on Wagtail:

class PricingPage(Page):
    plans = StreamField(
         [("plans", PlanListBlock())],
         use_json_field=True,
     )

     @property
     def plan_count(self) -> int:
         try:
              return self.plans[0].value.count
         except (IndexError, AttributeError):
             return 0

class PlanListBlock(blocks.StreamBlock):
     """A collection of price cards"""
     plan = PlanCardBlock()

class PlanCardBlock(blocks.StructBlock):
     """Price Card with a plan's name, price"""
     title = blocks.CharBlock(required=True, help_text="Plan's title")
     currency_symbol = blocks.CharBlock(required=True, max_length=3)
     unit_amount = blocks.DecimalBlock(min_value=0, max_value=100)

I'm having trouble testing the plan_count method. Specifically, I'm stuck trying to add a new plan to an existing pricing page with no plans programmatically (I'm on Wagtail 4.1).

My challenge is to take a PricingPage instance I use for tests and

Conventional Commits with a data prefix

I uploaded this for myself, mostly for committing blog articles. Would work just as well for many non-code, non-documentation commits. The Commitizen conventional commits implementation with one more field: `data:`

This is a branch of my conventionalish project.

Data Analysis

I started to learn Python and I've already got basic things on Python. I love statistics and I'm taking some classes about statistics at university.

So that's my question, where should I start to data Analysis with python

I asked that which I should follow the way

Thnx for all answers.

Django project complexity

How can I know if my Django projects are good enough and complex enough so I can present them as my portfolio projects?
Currently I have a to-do list (creating, updating and deleting tasks with login/register functions), a blog(similar to to-do list, a bit more complex), an app that tracks stocks prices using an API and I'm currently working kn a Ecommerce store(combining Django with JS).
Should I focus on improving these apps or should I create more complexed apps?

Scriptum: A command line utility for storing, documenting, and executing your project's scripts.

Scriptum is a command line utility for storing, documenting, and executing your project's scripts, written in Python.

With scriptum, you can easily configure and run your project's scripts, by defining them in a configuration file. Here is an example of a configuration file:

Updated documentation for ScreenPy which should help you understand Screenplay Pattern, we think, we hope.

'Sssup, snakes—

I'm back with some updated documentation for ScreenPy, which is our Screenplay Pattern base suite for Python. If you haven't heard of it—that's not surprising—it lets you write tests that look like this:

def testexample(Snoo: AnActor) -> None:
given(Snoo).wasableto(LogIn.using(USERNAME, PASSWORD))

when(Snoo).attemptsto(
Visit(POSTURL),
MakeNote.ofthe(VotesOnThePost()).as("votes before"),
Click.onthe(UPVOTEARROW),
)

then(Snoo).should(
See.the(VotesOnThePost(), IsEqualTo(thenoted("votes before") + 1),
)

We recently rewrote our entire documentation with a focus on showing how to build a suite using a made-up Ability, which showcases way more of the modular, composition-based approach that Screenplay Pattern uses.

Our goal is to present ScreenPy and Screenplay Pattern in a way that is easy to follow and hopefully exciting to read about. Please let

Enforcing fixed time step in FMI++ (fmipp)

I am learning python the hard way (at least i feel like it). I need to get an fixed step FMU running, to cosimulate with a multibody simulation Tool (MSC ADAMS). I chose fmipp, as it is quite powerful, but i cant get it to run with fixed step size.

Has anyone here ever done it?

R Git is for Data (CIDR 2023) - Extending Git to Support Large-Scale Data

Paper: https://www.cidrdb.org/cidr2023/papers/p43-low.pdf

Abstract:

Dataset management is one of the greatest challenges to the application of machine learning (ML) in the industry. Although scaling and performance have often been highlighted as the significant ML challenges, development teams are bogged down by the contradictory requirements of supporting fast and flexible data iteration while maintaining stability, provenance, and reproducibility. For example, blobstores are used to store datasets for maximum flexibility, but their unmanaged access patterns limit reproducibility. Many ML pipeline solutions to ensure reproducibility have been devised, but all introduce a degree of friction and reduce flexibility.

In this paper, we propose that the solution to the dataset management challenges is simple and apparent: Git. As a source control system, as well as an ecosystem of collaboration and developer tooling, Git has enabled the field of DevOps to provide both speed of iteration and reproducibility to source code. Git is not only already familiar to developers, but is also integrated into existing pipelines, which facilitates adoption. However, as we (and others) demonstrate, Git, as designed today, does not scale to the needs of ML dataset management. In this paper, we propose XetHub; a system that retains the Git user experience and ecosystem, but can scale to

D Microsoft ChatGPT investment isn't about Bing but about Cortana

I believe that Microsoft's 10B USD investment in ChatGPT is less about Bing and more about turning Cortana into an Alexa for corporates.
Examples: Cortana prepare the new T&Cs... Cortana answer that client email... Cortana prepare the Q4 investor presentation (maybe even with PowerBI integration)... Cortana please analyze cost cutting measures... Cortana please look up XYZ...

What do you think?

D Are there any papers on optimization-based approaches which combine learned parameter initializations with learned optimisers?

There are quite a few papers on optimisation-based meta-learning approaches for learning parameter initialisations (i.e. MAML and its derivatives) [1, 2\], and there are also many papers on learning optimisers [3\].

Question: Are there any papers which combine the two?

I am aware of some papers such as [4, 5\] which achieve this in some capacity indirectly/implicitly, but wondering if there are any other papers that I am not aware of, or do this explicitly? Thanks in advance.

Is it still relevant today to take a Python and Pandas course that was created two years ago?

I'm learning Python nowadays and I'm taking this course on freecodecamp

Is is still relevant today or a lot of things have changed in Python and Pandas?

I'm coming from R language so I have experience in R, SQL and Tableau. I chose this one because I liked the way they teach the course (there are projects).

I really appreciate your suggestions for other courses.

The interest here is in Data Analysis/Science and Automation. (If someone has taken this path before)

I really appreciate any help and thank you for your time.
