Poetry

Overview

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. ¹

• Poetry is very similar to PipEnv.
• It, also, doesn't come with Python by default, so you'll need to install it first.
• Two major benfits over pip are (same as pipenv):
  • Dependencies are installed in a virtualenv, so you don't have to worry about installing them in the system path.
  • It automatically captures installed dependencies in files to generate an exact replica of the environment packages.
    • I'd then check the dependeinces file into my code repository and is always available for me to use and share.
    • Unlike in pip where you specifically need to freeze a snapshot of the entire virtual env with all of its dependencies.
    • It generates 2 files: poetry.lock and pyproject.toml.
