Have you written Python packages (wheel, publishing to registry)?

Yes, I have created Python packages and published them in registries such as PyPI.

The process usually involves the following steps:

1. Creating the package structure with setup.py or pyproject.toml files, where package metadata (name, version, dependencies) are described.
2. Writing code and tests inside the package.
3. Building the package into a wheel file using python setup.py bdist_wheel or python -m build.
4. Publishing the package to PyPI using twine upload dist/*.

Example setup.py for a simple package:

from setuptools import setup, find_packages

setup(
    name='mypackage',
    version='0.1.0',
    packages=find_packages(),
    install_requires=['requests'],
)

This allows you to distribute your code and use it in other projects through standard Python tools.
