Ask the author? https://github.com/aswild/python-gpiod
Maybe read the source code for hints?

It is by design. `sorted` returns a list, while `reversed` returns an iterator.
Iterators are exhaust-able, and not reusable. So be mindful of this and if you
are going to "re-use” the sequence returned by iterator, convert it to list
first.
Have a look at `itertools` library, which contains a
I am using the gpiod package for manipulating GPIO inputs/outputs on a
Beaglebone Black SBC (like a Raspberry Pi but with more flexible I/O).
Mostly I am managing to get things to work as I want but better

For example, when one has found an I/O pin (a

# rev is now destroyed
So reversed() results can only be iterated once unlike so

This also does not work with the older way of putting the name of a class
