Which Is the Best Python Web Framework: Django, Flask, or FastAPI?

Search for Python web frameworks, and three names will consistently come up: Django, Flask, and FastAPI. Our latest Python Developer Survey Results confirm that these three frameworks remain developers’ top choices for backend web development with Python. All three frameworks are open-source and compatible with the latest versions of Python.  But how do you determine […]

Decorator JITs - Python as a DSL

Spend enough time looking at Python programs and packages for machine learning, and you'll notice that the "JIT decorator" pattern is pretty popular. For example, this JAX snippet:

import jax.numpy as jnp
import jax

@jax.jit
def add(a, b):
  return jnp.add(a, b)

# Use "add" as a …

Improving licence metadata

What? #

PEP 639 defines a spec on how to document licences used in Python projects.

Instead of using a Trove classifier such as “License :: OSI Approved :: BSD License”, which is imprecise (for example, which BSD licence?), the SPDX licence expression syntax is used.

How? #

pypproject.toml #

Change pyproject.toml as follows.

I usually use Hatchling as a build backend, and support was added in 1.27:

 [build-system]
 build-backend = "hatchling.build"
 requires = [
 "hatch-vcs",
- "hatchling",
+ "hatchling>=1.27",
 ]

Replace the freeform license field with a valid SPDX license expression, and add license-files which points to the licence files in the repo. There’s often only one, but if you have more than one, list them all:

 [project]
 ...
-license = { text = "MIT" }
+license = "MIT"
+license-files = [ "LICENSE" ]

Optionally delete the deprecated licence classifier:

 classifiers = [
 "Development Status :: 5 - Production/Stable",
 "Intended Audience :: Developers",
- "License :: OSI Approved :: MIT License",
 "Operating System :: OS Independent",

For example, see humanize#236 and prettytable#350.

Upload #

Then make sure to use a PyPI uploader that supports this.

I recommend using Trusted Publishing which I use with pypa/gh-action-pypi-publish to deploy from GitHub Actions. I didn’t need to make any changes here, just make a release as usual.

Result #

PyPI #

PyPI shows the new metadata:

Screenshot of PyPI showing licence expression: BSD-3-Clause

pip #

pip can also show you the metadata:

❯ pip install prettytable==3.13.0
❯ pip show prettytable
Name: prettytable
Version: 3.13.0
...
License-Expression: BSD-3-Clause
Location: /Library/Frameworks/Python.framework/Versions/3.13/lib/python3.13/site-packages
Requires: wcwidth
Required-by: norwegianblue, pypistats

Thank you! #

A lot of work went into this. Thank you to PEP authors Philippe Ombredanne for creating the first draft in 2019, to C.A.M. Gerlach for the second draft in 2021, and especially to Karolina Surma for getting the third draft finish line and helping with the implementation.

And many projects were updated to support this, thanks to the maintainers and contributors of at least:

get in JavaScript is the same as property in Python

Prefix a function, in an object or class, with `get` and then that acts as a function call without brackets. Just like Python's `property` decorator.

About dropping Python 2.7 support in psutil, 3 years ago I stated:

Not a chance, for many years to come. [Python 2.7] currently represents 7-10% of total downloads, meaning around 70k / 100k downloads per day.

Only 3 years later, and to my surprise, downloads for Python 2.7 …

Avoid over-commenting in Python

When do you need a comment in Python and when should you consider an alternative to commenting?

Table of contents

  1. Documenting instead of commenting
  2. Non-obvious variables and values
  3. Unnamed code blocks
  4. Missing variables due to embedded operations
  5. Indexes instead of variables
  6. Comment the "why" more than the "what"
  7. Consider whether there's a better alternative to your comments

Documenting instead of commenting

Here is a comment I would not write in my code:

def first_or_none(iterable):
    # Return the first item in given iterable (or None if empty).
    for item in iterable:
        return item
    return None

That comment seems to describe what this code does... so why would I not write it?

I do like that comment, but I would prefer to write it as a docstring instead:

def first_or_none(iterable):
    """Return the first item in given iterable (or None if empty)."""
    for item in iterable:
        return item
    return None

Documentation strings are for conveying the purpose of function, class, or module, typically at a high level. Unlike comments, they can be read by Python's built-in help function:

>>> help(first_or_none)
Help on function first_or_none in module __main__:

first_or_none(iterable)
    Return the first item in given iterable (or None if empty).

Docstrings are also read by other documentation-oriented tools, like Sphinx.

Non-obvious variables and values

Here's a potentially helpful comment:

Modern REST API Tutorial in Python

Modern REST API Tutorial in Python

2025-02-12, by Dariusz Suchojad

Great APIs don't win theoretical arguments - they just prefer to work reliably and to make developers' lives easier.

Here's a tutorial on what building production APIs is really about: creating interfaces that are practical in usage, while keeping your systems maintainable for years to come.

Sound intriguing? Read the modern REST API tutorial in Python here.

pass using stateless OpenPGP command line interface

Yesterday I wrote about how I am using a different tool for git signing and verification. Next, I replaced my pass usage. I have a small patch to use stateless OpenPGP command line interface (SOP). It is an implementation agonostic standard for handling OpenPGP messages. You can read the whole SPEC here.

Installation

cargo install rsop rsop-oct

And copied the bash script from my repository to the path somewhere.

The rsoct binary from rsop-oct follows the same SOP standard but uses the card to signing/decryption. I stored my public key in ~/.password-store/.gpg-key file, which is in turn used for encryption.

Usage

Here nothing changed related my daily pass usage, except the number of time I am typing my PIN :)
