PEP 758 – Allow except and except* expressions without parentheses

PEP 758 – Allow except and except* expressions without parentheses https://peps.python.org/pep-0758/

# Abstract

This PEP proposes to allow unparenthesized except and except* blocks in Python’s exception handling syntax. Currently, when catching multiple exceptions, parentheses are required around the exception types. This was a Python 2 remnant. This PEP suggests allowing the omission of these parentheses, simplifying the syntax, making it more consistent with other parts of the syntax that make parentheses optional, and improving readability in certain cases.

# Motivation

The current syntax for catching multiple exceptions requires parentheses in the except expression (equivalently for the except* expression). For example:

try:
...
except (ExceptionA, ExceptionB, ExceptionC):
...

While this syntax is clear and unambiguous, it can be seen as unnecessarily verbose in some cases, especially when catching a large number of exceptions. By allowing the omission of parentheses, we can simplify the syntax:

try:
...
except ExceptionA, ExceptionB, ExceptionC:
...

This change would bring the syntax more in line with other comma-separated lists in Python, such

Lazywarden: Automate your Bitwarden Backups and Imports with Total Security! ☁️🔐🖥️

What My Project Does

A few weeks ago, I launched Lazywarden, a tool designed to make life easier for those of us who use Bitwarden or Vaultwarden. It automates the process of backing up and importing passwords, including attachments, in a secure and hassle-free way. You can check it out here: https://github.com/querylab/lazywarden

Target Audience

Anyone who wants to automate backups and imports of passwords securely and efficiently, while using Bitwarden or Vaultwarden.

Comparison

While Bitwarden is excellent for managing passwords, automating processes like cloud backups, integrating with other services, or securing your data locally can be tricky. Lazywarden simplifies all this with a noscript that does the heavy lifting for you. 😎

I'm open to any feedback, suggestions, or ideas for improvement. Feel free to share your thoughts or contribute to the project! 🤝

Thanks for reading, and I hope you find Lazywarden as useful as I do. 💻🔑

What does everyone use for Django emails?

Hi, I'm wondering what everyone uses for email templates and sending. I'm a hobbist but have a couple random sites, one with 800 users. I've always used the Django emails and setup templates for them within Django. I know this is my skill level but they always look basic and blah. Is there a better way?

deployment with nginx and gunicorm

Hello there,

Should I deploy my flask application with gunicorn, and nginx in the same container?

And for every flask microservice there should be an nginx deployed? like 5 nginx for 5 microservice ?

It feels like kind of antipattern (but what do I know) but recently I came across something like that.

Also, could you share examples of production level deployment, if you know any examples out there

Thanks, and sorry for my bad english, if any mistakes

I never realized how complicated slice assignments are in Python...

I’ve recently been working on a custom mutable sequence type as part of a personal project, and trying to write a __setitem__ implementation for it that handles slices the same way that the builtin list type does has been far more complicated than I realized, and left me scratching my head in confusion in a couple of cases.

Some parts of slice assignment are obvious or simple. For example, pretty much everyone knows about these cases:

>>> l = 1, 2, 3, 4, 5
>>> l0:3 = 3, 2, 1
>>> l
3, 2, 1, 4, 5

>>> l3:0:-1 = 3, 2, 1
>>> l
1, 2, 3, 4, 5

That’s easy to implement, even if it’s just iterative assignment calls pointing at the right indices. And the same of course works with negative indices too. But then you get stuff like this:

>>> l = 1, 2, 3, 4, 5
>>> l3:6 = 3, 2, 1
>>> l
1, 2, 3, 3, 2, 1

3.13 JIT compiler VS Numba

Python 3.13 comes with a new Just in time compiler (JIT). On that I have a few questions/thoughts on it.



1. About CPython3.13 JIT I generally hear:

we should not expect dramatic speed improvements
This is just the first step for Python to enable optimizations not possible now, but is the groundwork for better optimizations in the future



2. How does this JIT in the short term or long term compare with Numba?

3. Are the use cases disjoint or a little overlap or a lot overlap?

4. Would it make sense for CPython JIT and Numba JIT to be used together?

Any better way between Javanoscript and Django to communicate with each other?

I am designing a front-end for an API of mine. As of now the only way for the Javanoscript and Django to communicate is from cookies.

For example, If a sign in attempt is made with incorrect credentials, the server receives the sign in form, makes a POST request to the API, the API returns an error message that the credentials are incorrect, the Django server makes a temporary cookie named "errorMessage" and redirects the user to the Sign In page again. The cookie then is read and deleted by the Javanoscript to initiate an alert() function with the error message to let the user know that the credentials were wrong.

Is there any better, simple or efficient way?

R Meta releases SOTA video generation and audio generation that's less than 40 billion parameters.

Today, Meta released SOTA set of text-to-video models. These are small enough to potentially run locally. Doesn't seem like they plan on releasing the code or dataset but they give virtually all details of the model. The fact that this model is this coherent already really points to how much quicker development is occurring.

This suite of models (Movie Gen) contains many model architectures but it's very interesting to see training by synchronization with sounds and pictures. That actually makes a lot of sense from a training POV.

Segregate By Date: Sort your photos into year and month folders based on filename and EXIF metadata

What My Project Does

This Python code I developed can read a folder containing images and can sort them into folders- parent folder name would be "2024", "2023", etc and child folders would be "Jan", "Feb", etc. The program can read files no matter how they are nested or how many sub-folders there are or where they came from. For instance, if we have 100 files directly in a folder with normal names, 50 files with timestamps in the filename (like IMG_20210912_120000.jpg), 100 files already sorted into years but not month, 50 files already fully sorted into month and year. Once the program is run, all 300 files will be properly sorted into year and month folders.

You can also set the input folder as a new set of images and the output folder a previous output of this program, and the output folder will be modified in place to generate a new fully sorted set of photos (in other words, previous results are implicitly merged with the new one).

Target Audience

1. People or families who regularly take pictures on multiple devices, later wanting to store them all in one place, perhaps to maintain a long-term memories album, or to

I made a dumb simple GMAIL client... only for sending emails from gmail.

I wanted to automatically send emails from my gmail account but didn't want to go through the whole Google Cloud Platform / etc. setup... this just requires an app passcode for your gmail.

(note: I'm not great at packaging so currently only works from GitHub install)

# What my project does:

Lets you use your gmail and send it in Python without all the GCP setup.

# Target audience:

Simpletons like myself.

# Comparison:

I couldn't find an easy way to use Python gmail without all the complicated Google Cloud Platform jazz... so if you're only wanting to automatically send emails with your gmail account, this is for you!

Let me know what you guys think! Look at the source, it's pretty simple to use haha.

ovld - fast and featureful multiple dispatch

## What My Project Does

[ovld](https://github.com/breuleux/ovld) implements multiple dispatch in Python. This lets you define multiple versions of the same function with different type signatures.

For example:

import math
from typing import Literal
from ovld import ovld

@ovld
def div(x: int, y: int):
return x / y

@ovld
def div(x: str, y: str):
return f"{x}/{y}"

@ovld
def div(x: int, y: Literal[0]):
return math.inf

assert div(8, 2) == 4
assert div("/home", "user") == "/home/user"
assert div(10, 0) == math.inf

## Target Audience

Ovld is pretty generally applicable: multiple dispatch is a central feature of several programming languages, e.g. Julia. I find it particularly useful when doing work on complex heterogeneous data structures, for instance walking an AST, serializing/deserializing data, generating HTML representations of data, etc.

Free Python Learning with Literal Baby Steps

I was using Coddy, but then I ran into a paywall and couldn't execute any more functions unless I waited a day. I'm looking for something that helps me to repeat the same things over and over to memorize syntax and learn.

For example, SQL Climber has been wonderful with very slowly learning SQL and repeating the same commands over and over for me to memorize them, and very slowly progressing to more concepts. I'm looking for something similar, but with Python; and completely free. I tried Exercism, but I didn't find it very accessible. Confusing to navigate, and I got stuck on the first main exercise of "cooking a lasagne" because it didn't explain very well what I'm putting in and where and why. I also tried Hack in Science but it progressed way too fast and was more focused on the problem solving aspect, when all I want is learning about the syntax and repeating to memorize it.


I also want something with an online editor that checks my work and then moves on if it's correct (not a book or online book).
