Write a program that, given a word, computes the scrabble score for that word.
## Letter Values
You'll need these:
```
Letter                           Value
A, E, I, O, U, L, N, R, S, T       1
D, G                               2
B, C, M, P                         3
F, H, V, W, Y                      4
K                                  5
J, X                               8
Q, Z                               10
```
```if:ruby,javascript,cfml
There will be a preloaded hashtable `$dict` with all these values: `$dict["E"] == 1`. 
```
```if:haskell
There will be a preloaded list of `(Char, Int)` tuples called `dict` with all these values.
```
```if:python
There will be a preloaded dictionary `dict_scores` with all these values: `dict_scores["E"] == 1`
```
## Examples
```
"cabbage" --> 14
```
"cabbage" should be scored as worth 14 points:
- 3 points for C
- 1 point for A, twice
- 3 points for B, twice
- 2 points for G
- 1 point for E
And to total:
`3 + 2*1 + 2*3 + 2 + 1` = `3 + 2 + 6 + 3` = `14`
Empty string should return `0`. The string can contain spaces and letters (upper and lower case), you should calculate the scrabble score only of the letters in that string.
```
""           --> 0
"STREET"    --> 6
"st re et"    --> 6
"ca bba g  e" --> 14
```
def scrabble_score(st): 
    st = st.upper()
    key = {'AEIOULNRST': 1, 'DG': 2, 'BCMP': 3, 'FHVWY': 4, 'K': 5, 'JX': 8, 'QZ': 10}
    score = 0
    for letter in st:
        for string in key.keys():
            if letter in string:
                score += key[string]
    return score
def scrabble_score(st): 
    st = st.upper()
    key = {'AEIOULNRST': 1, 'DG': 2, 'BCMP': 3, 'FHVWY': 4, 'K': 5, 'JX': 8, 'QZ': 10}
    score = 0
    for letter in st:
        for string in key.keys():
            if letter in string:
                score += key[string]
    return score
