Python

In a requirements-*.in file, at the top of the file, are lines with -c and -r flags followed by a requirements-*.in file. Uses relative paths (ignoring URLs).

Say have docs/requirements-pip-tools.in

-r ../requirements/requirements-prod.in
-c ../requirements/requirements-pins-base.in
-c ../requirements/requirements-pins-cffi.in

...

The intent is compiling this would produce docs/requirements-pip-tool.txt

But there is confusion as to which flag to use. It's non-obvious.

constraint

Subset of requirements features. Intended to restrict package versions. Does not necessarily (might not) install the package!

Does not support:

editable mode (-e)
extras (e.g. coverage[toml])

Personal preference

always organize requirements files in folder(s)
don't prefix requirements files with requirements-, just doing it here
DRY principle applies; split out constraints which are shared.

D2 (d2lang) Python Wrapper (lemm.ee)

submitted 1 year ago by daco@lemm.ee to c/python@programming.dev

0 comments fedilink

Hi,

I wanted to use d2 in an environment where I could only install python and npm packages.

Given that, and that I could not find any other solution, I made d2-python-wrapper, a small python wrapper that bundles the d2 binaries.

Now you can use d2 from python like this:

from d2_python import D2

d2 = D2()

# Simple diagram
with open("test.d2", "w") as f:
    f.write("x -> y")

# Default SVG output
d2.render("test.d2", "output.svg")

# PDF output with specific theme
d2.render("test.d2", "output.pdf", format="pdf", theme="1")

The class just wraps the bin, so it works and supports the same as the bin. There is a GitHub Action that gets the bins for each platform (mac, win, linux) from the releases in this repo and publishes it to pip.

You can install this using

pip install d2-python-wrapper

Here is a short post with more context.

Just in case It's useful for anyone. 😁

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

submitted 1 year ago* (last edited 1 year 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

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

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

33 comments fedilink

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!)
