Load pyproject.toml information into your project. If you want to centralize your version information of your package at e.g. your pyproject.toml, then you simply might want to use

from importlib_metadata import version
__version__ = version('pyklopp')

to load your package version. This actually accesses the installed package in your current environment and retrieves the metadata version from there. However, if you want to actually access content of your (probably not installed) pyproject.toml, you can use pip install poetry_project

Usage:

from poetry_project import get_version
__version__ = get_version('your_package_name')

or:

import your_package  # must contain a pyproject.toml
from poetry_project import get_version
__version__ = get_version('your_package')

Importantly note, that you need to ship your pyproject.toml explicitly to your package. This requires additional configuration, e.g. by adding the file to the include-statement within your pyproject.toml:

[tool.poetry]
include = [
    "pyproject.toml"
]

Only then this file gets actually packaged when delivered e.g. by PyPi.

poetry build twine upload dist/*
