>>> ff=sorted({1: 'D', 2: 'B', 3: 'B', 4: 'E', 5: 'A'})
>>> ff
[1, 2, 3, 4, 5]
sorted({1: 'D', 2: 'B', 3: 'B', 4: 'E', 5: 'A'}) is equivalent to
sorted(iter({1: 'D', 2: 'B', 3: 'B', 4: 'E', 5: 'A'}))
and iter(dict) iterates over the dict keys, so when you do
iter({1: 'D', 2: 'B', 3: 'B', 4: 'E', 5: 'A'}) you essentially get
[1,2,3,4,5]
and sorted([1,2,3,4,5]) returns [1,2,3,4,5]
