What the code was meant to do, written into the code itself as a docstring

Cache implementation with per-item time-to-live (TTL) value. This class associates a time-to-live value with each item. Items that expire because they have exceeded their time-to-live will be removed automatically. If no expired items are there to remove, the least recently used items will be discarded first to make space when necessary.

The change

3232 def __getitem__(self, key, cache_getitem=LRUCache.__getitem__):
3333 value, link = cache_getitem(self, key)
3434 if link.data[1] < self.__timer():
35- raise KeyError('%r has expired' % key)
35+ raise KeyError(key)
3636 return value

The check that tells the two apart

fail→pass·tests/test_ttlcache.py::TTLCacheTest::test_ttl_tuple_key

Check file tests/test_ttlcache.py, taken without changes from the fix and copied onto the older code, so the exact same check runs against both versions.
