Python3: Remove Duplicate Key-Value Pair and Add Array : I have an ordered dictionary and an array of int both of the same index size:

```
Dict = {“A”: “Apple”, “A”: “Ant”, “A”: “Apple”, “B”: “Ball”, “B”: “Beach”, “C”: “Cat, “C”: “Cat”, “D”: “Ball”}
Arr   = [1, 2, 3, 4, 5, 6, 7, 8]
```
I want to remove duplicates in the dictionary (non-unique key-value pairs) and also sum the ints in the array as such:

```
New Dict = {“A”: “Apple”, “A”: “Ant”, “B”: “Ball”, “B”: “Beach”, “C”: “Cat, “D”: “Ball”}
New Arr   = [4, 2, 4, 5, 13, 8]
```

Any suggestions on an elegant way to approach this problem?
