PUG ( web template engine ) for Python 🐍 (programming.dev)

submitted 1 week ago* (last edited 5 days ago) by Rick_C137@programming.dev to c/python@programming.dev

0 comments fedilink

Hi,

I've discover haml and pug [^1] ( both web template engine )

It's totally Pytonic ! ( and make even more sense to use it with python rather than JS 🤮 )

I've look, if it exist for Python, but so far, I've found only

The first, only convert pug into another template :/
The second, didn't pass the alpha version.
The third, require dependence, not maintained etc.. \

So I didn't found a Python package that could do haml/pug to html directly, without too much dependence...

For example:

From

html
  head title Example for Python discuss
  body
    h1 Hello world
    p This is a paragraph.

<html>
  <head>
    <title>Example for Python discuss</title>
  </head>
  <body>
    <h1>Hello world</h1>
    <p>This is a paragraph.</p>
  </body>
</html>

Do you know if such thing exist ?
If not, I will build my own (FLOSS). ( I'm open to any advice to do so :) )

Thanks

[^1]:Pug is a template engine heavily influenced by Haml and implemented with JavaScript 🤮 for Node.js

Hi,

I'm following my previous post

Thanks.

What would Enaml 2.0 look like? | nucleic/enaml | Declarative UI (github.com)

submitted 2 weeks ago by Andy@programming.dev to c/python@programming.dev

0 comments fedilink

From Enaml's docs:

Enaml brings the declarative UI paradigm to Python in a seamlessly integrated fashion. The grammar of the Enaml language is a strict superset of Python. This means that any valid Python file is also a valid Enaml file, though the converse is not necessary true. The tight integration with Python means that the developer feels at home and uses standard Python syntax when expressing how their data models bind to the visual attributes of the UI.

. . .

Enaml’s declarative widgets provide a layer of abstraction on top of the widgets of a toolkit rendering library. Enaml ships with a backend based on Qt5/6 and third-party projects such as enaml-web and enaml-native provides alternative backends.

A maintainer of Enaml has just opened a brainstorm discussion on the next major development goals.

It's a project I've long admired, though rarely used, and I'd love to see it get some attention and a revamp. I think the bar these days has been raised by projects like QML and Slint, which provide a great context in which to set new goals.

Confused about logical operators (i.e. "comparison operators", or "boolean operators") in Python (lemmy.blahaj.zone)

submitted 2 weeks ago* (last edited 1 week ago) by EveryMuffinIsNowEncrypted@lemmy.blahaj.zone to c/python@programming.dev

Note: The attached image is a screenshot of page 31 of Dr. Charles Severance's book, Python for Everybody: Exploring Data Using Python 3 (2024-01-01 Revision).

I thought = was a mathematical operator, not a logical operator; why does Python use

>= instead of >==, or <= instead of <==, or != instead of !==?

Thanks in advance for any clarification. I would have posted this in the help forums of FreeCodeCamp, but I wasn't sure if this question was too.......unspecified(?) for that domain.

Cheers!

Edit: I think I get it now! Thanks so much to everyone for helping, and @FizzyOrange@programming.dev and @itslilith@lemmy.blahaj.zone in particular! ^_^

hugovk.github.io/free-threaded-wheels/ tracks how many of the top 360 PyPI packages have free-threaded wheels.

Green packages (currently 3%) offer has free-threaded wheels

Uncoloured packages (82%) offer pure-Python wheels

Orange packages (16%) have no wheels ready for free-threading (yet!)

See also Quansight Labs' https://py-free-threading.github.io/tracking/ for a smaller yet fine-grained tracker that also includes build tools.

First time using the walrus operator! (programming.dev)

submitted 1 month ago by Hammerheart@programming.dev to c/python@programming.dev

2 comments fedilink

I am working on a rudimentary Breakout clone, and I was doing the wall collision. I have a function that I initially treated as a Boolean, but I changed it to return a different value depending on which wall the ball hit. I used the walrus operator to capture this value while still treating the function like a bool. I probably could have just defined a variable as the function's return value, then used it in an if statement. But it felt good to use this new thing I'd only heard about, and didn't really understand what it did. I was honestly kind of surprised when it actually worked like I was expecting it to! Pretty cool.

Multiple process or threads? And, why? (programming.dev)

submitted 1 month ago by anzo@programming.dev to c/python@programming.dev

10 comments fedilink

(For context, I'm basically referring to Python 3.12 "multiprocessing.Pool Vs. concurrent.futures.ThreadPoolExecutor"...)

Today I read that multiple cores (parallelism) help in CPU bound operations. Meanwhile, multiple threads (concurrency) is due when the tasks are I/O bound.

Is this correct? Anyone cares to elaborate for me?

At least from a theorethical standpoint. Of course, many real work has a mix of both, and I'd better start with profiling where the bottlenecks really are.

If serves of anything having a concrete "algorithm". Let's say, I have a function that applies a map-reduce strategy reading data chunks from a file on disk, and I'm computing some averages from these data, and saving to a new file.

How encrypt email with a GnuPG public key ? [ solved ] (programming.dev)

submitted 1 month ago* (last edited 1 month ago) by Rick_C137@programming.dev to c/python@programming.dev

6 comments fedilink

Hi,

I'm already using

from smtplib import SMTP_SSL
from email.message import EmailMessage

To send emails.

Now I would like to be able to encrypt them with the public key of the recipient. ( PublicKey.asc )

an A.I provide me this

import smtplib
from email.message import EmailMessage
from cryptography.hazmat.primitives.asymmetric import ec
from cryptography.hazmat.primitives import serialization
from cryptography.hazmat.primitives.ciphers.aead import AESGCM

# Load the ECC public key from the .asc file
with open('recipient_public_key.asc', 'rb') as key_file:
    public_key_bytes = key_file.read()
public_key = ec.EllipticCurvePublicKey.from_public_bytes(
    ec.SECP384R1(),
    public_key_bytes
)

# Create the email message
msg = EmailMessage()
msg.set_content('This is the encrypted email.')
msg['Subject'] = 'Encrypted Email'
msg['From'] = 'you@example.com'
msg['To'] = 'recipient@example.com'

# Encrypt the email message using the ECC public key
nonce = bytes.fromhex('000102030405060708090a0b0c0d0e0f')
cipher = AESGCM(public_key.public_key().secret_key_bytes)
ciphertext = cipher.encrypt(nonce, msg.as_bytes(), None)

# Send the encrypted email
server = smtplib.SMTP('smtp.example.com')
server.send_message(msg, from_addr='you@example.com', to_addr='recipient@example.com')
server.quit()

# Save the encrypted email to a file
with open('encrypted_email.bin', 'wb') as f:
    f.write(ciphertext)

I like the approach, only one "low level" import cryptography

but the code seem wrong. if the body has been encrypted as ciphertext I don't see this one included while sending the email.

How are you doing it ? or do you have good tutorial, documentations ? because I found nothing "pure and simple" meaning not with of unnecessary stuff.

Thanks.
