Poetry
Poetry is a tool for dependency management and packaging in Python. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.

Usage
Install packages
The install command reads the pyproject.toml file from the current project, resolves the dependencies, and installs them.
poetry install
You can specify to the command that you don't want the development dependencies installed by passing the --no-dev option.
poetry install --no-dev
Add packages
The add command adds required packages to your pyproject.toml and installs them.
