Finding sets by set code pulls in all sets

[MichaelJAndy]

The following code returns 448 results where it should only return one.

from mtgsdk import Set
sets = Set.find('ktk').all()
len(sets)

I obtained this snippet from the code examples on the repo readme https://github.com/MagicTheGathering/mtg-sdk-python/blob/master/README.md

Don't use .all() with Set.find(), or Card.find() for that matter.

The instructions on the readme say to use Set.find('ktk')
When you call .all() on the returned object it gets all sets.
