Your fish-sense is working correctly. Both of those are hard-coding the path,
when the Python import mechanism is designed so you don't do that.

Instead, to run the package, first install the package.

To install the package, use the Pip tool. This comes standard when you install
Python 3.

By installing your code, you make it available to be discovered by Python's
normal import mechanism.

So, choose how you want to install the package:

* To install for normal use, ? ?python3 -m pip install ? |? ?.

* To install for use only by the current user, add the ? ?--user? ? option.

* To install for use while also developing, add the ? ?--editable? ? option.

See the ? ?python3 -m pip --help? ? document for details about what all that
does.
