In search of a better way to extract project details from a pyproject.toml file

I use poetry to manage my Python projects, which means I have useful information in a pyproject.toml file at the root of my project directory, including:

• Author name and possibly contact details
• Project name
• Project description
• Version

A well-behaved tool should obviously include some or all of this information when invoked at the command line or via its GUI. To avoid repeating myself (and having data get out of sync) I prefer to extract the info from the pyproject.toml file to use in my Python source. I use a small Python script to do this (see here). This script checks for a *pyproject.toml" file in:

• the sys._MEIPASS attribute (present if the tool is running as a PyInstaller executable)
• the directory the script is in
• one directory up from the script

If it finds a pyproject.toml file in any of those, it stops looking and returns some project details which the source can use.

This works but it feels rather hacky. I would love to be able to import the relevant details from the pyproject.toml file directly into my source anywhere in my project structure without worrying about where exactly it came from on the file system. I have not been able to find or figure out a way to do this. If anyone can point me in the right direction I would be very happy to stop using this hacky technique.
