What operating system do you use, what version of Python, and what package manager do you use?

I use the Ubuntu 22.04 LTS operating system.

Python version — 3.10.6.

As a package manager, I use pip, which comes with Python, and for managing virtual environments — venv.

Example of installing a package:

python3 -m venv env
source env/bin/activate
pip install requests

I also sometimes use Poetry for more convenient dependency management and package publishing.
