Subject of your post is confusing for me. "Path expressions" is a term from 
PageTemplates world. Look at path expressions:
<span tal:content="request/parameter"></span>
or
<span tal:content="python:path('options/parameter')"></span>

> path="animals"
path is a local variable (for your 'Script (Python)')

Here you try to find an object (Folder) called 'path' inside object 
called 'sections'.

is not present.
Yup, there is no 'path' object inside 'sections'.

because there is 'animals' object

Script?
Try: context.sections[path].contentValues()
