Python

Edit: The key was using msys2. After installing Gtk3 and PyGObject following the PyGObject guide for msys2 everything worked fine. Packaging with PyInstaller and nuitka was fine.

I've been developing an image halftoning app for a while using GTK on Linux, thinking GTK is cross platform, and delaying testing it on Windows for quite some time.

Today I decided to finally install Windows 10 (for the first time in more than a decade) on a separate machine and see what works and what does not.

For the past few hours I've been through hell trying to get GTK3 to work. I've followed multiple guides, none of which worked, including wingtk.

Furthermore, even if I successfully compile (or install) GTK, would it be possible to package it all up using something like PyInstaller or nuitka.

At this point I'm thinking of keeping the functions and writing a whole new GUI in Tk for the Windows port, as at least that seems to work.

Am I missing something?

I've just create a little script to install pip in the latest Pythonista with comfort configuration, as I suppose.

This could probably be useful to someone other than me.

I want to build a python package using setuptools. The folder structure of the project is the following (some non-essential parts have been deleted):

energy-monitor
├── config
│ ├── config.yml
│ └── secrets.yml
├── data
│ └── cpu_tdp.json
├── energy_monitor
│ ├── core
│ │ ├── gui.py
│ │ ├── __init__.py
│ ├── data
│ │ └── tableExport.json
│ ├── __init__.py
│ ├── main.py
│ └── utils
│     ├── api_calls.py
│     └── __init__.py
├── energy-monitor.py
├── LICENSE
├── MANIFEST.in
├── pyproject.toml
├── README.md
└── requirements.txt

The content of the pyproject.toml file is the following (some non-essential parts have been deleted):

[build-system]
requires = ["setuptools>=68.0"]
build-backend = "setuptools.build_meta"

[project]
name = "energy_monitor"
version = "0.0.1"
description = "Energy monitor"
readme = "README.md"
requires-python = ">=3.11"
license = {text = "GPLv3"}
classifiers = [
  "Programming Language :: Python :: 3",
  "Operating System :: OS Independent",
]
dynamic = ["dependencies"]

[tool.setuptools.dynamic]
dependencies = {file = ["requirements.txt"]}

[tool.setuptools]
packages = [
  "energy_monitor", 
  "energy_monitor.core", 
  "energy_monitor.utils"
]
include-package-data = true

[project.scripts]
energy-monitor = "energy_monitor.main:main"

Finally, the content of the MANIFEST.in file is the following:

include README.md
include LICENSE
graft config

I generate the package with python -m build and install the .tar.gz archive with pipx. According to setuptools documentation, I expect to find my config folder, together with README and LICENSE in the interpreter directory (site-packages) after the installation. However, this doesn't happen and I cannot run the app becase it complains that it doesn't find the config. What am I missing?

I can't give you the code because this is work related, and I couldn't make a minimal code that mimics the behavior.

My of my programs at work is a log parser, it reads syslog and use compiled regex pattern to match syslog, the whole program looks like this

If match := pattern.match(line):
  Do this
elif match := pattern2.match(line):
  Do that
…

During almost two years of me developing the programs, there are more patterns and more things to do and it gets slower.

But I recently figure out that if I commented out Do that and replace it with pass, my program speeds up, even if pattern2 never matches in my test case.

More strange thing is that in my attempts to use cProfile to profile things, my program runs 2.5x to 3x faster by just doing

from cProfile import Profile
with Profile() as profile:
  main()

I don't even call anything with profile variable and it speeds up my program, why is that?

The thing I love about python is it's elegance; and I thing that is partially due to its syntactic sugar. Between list comprehensions, destructuring, enumerators, generators with yield, and a bunch more, what is your favorite

I'm talking about stuff like this: [file.unlink() for file in files] instead of the more verbose but maybe easier to grasp for python noobs:

for file in files:
    file.unlink()

Maybe with a bit more context:

def _cleanup(self) -> None:                                                                                                                                                                                                             
    dirs, files = partition(lambda f: f.is_file(), self._tmp_dir.rglob("*"))                                                                                                                                                            
    [file.unlink() for file in files]                                                                                                                                                                                                   
    [dir.rmdir() for dir in dirs]                                                                                                                                                                                                       
    self._tmp_dir.rmdir()
