You have duplicate keys here, which becomes obvious when you spell out the
values
testdict = {"filled": "apple", "filled": "banana", ...}
When you do that, the last value ("banana") wins, all others (e. g. "apple")
are dropped.

A dictionary is spot-on, but you have to use the unique "apple",
"banana",... as keys:
>>> status = {"apple": "filled", "banana": "filled", "cake": "empty"}
>>> for item in status:
... if status[item] == "filled":
... print(item)
...
apple
banana
Could it be that you just confused dict keys with dict values?
