# Scrabble Score
|
|
|
|
Given a word, compute the scrabble score for that word.
|
|
|
|
## Letter Values
|
|
|
|
You'll need these:
|
|
|
|
```text
|
|
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
|
|
```
|
|
|
|
## Examples
|
|
|
|
"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`
|
|
- = `5 + 9`
|
|
- = 14
|
|
|
|
## Extensions

## Exception messages
|
|
|
|
Sometimes it is necessary to raise an exception. When you do this, you should include a meaningful error message to
|
|
indicate what the source of the error is. This makes your code more readable and helps significantly with debugging. Not
|
|
every exercise will require you to raise an exception, but for those that do, the tests will only pass if you include
|
|
a message.
|
|
|
|
To raise a message with an exception, just write it as an argument to the exception type. For example, instead of
|
|
`raise Exception`, you should write:
|
|
|
|
```python
|
|
raise Exception("Meaningful message indicating the source of the error")
|
|
```
|
|
|
|
## Running the tests
|
|
|
|
To run the tests, run the appropriate command below ([why they are different](https://github.com/pytest-dev/pytest/issues/1629#issue-161422224)):
|
|
|
|
- Python 2.7: `py.test scrabble_score_test.py`
|
|
- Python 3.4+: `pytest scrabble_score_test.py`
|
|
|
|
Alternatively, you can tell Python to run the pytest module (allowing the same command to be used regardless of Python version):
|
|
`python -m pytest scrabble_score_test.py`
|
|
|
|
### Common `pytest` options
|
|
|
|
- `-v` : enable verbose output
|
|
- `-x` : stop running tests on first failure
|
|
- `--ff` : run failures from previous test before running other test cases
|
|
|
|
For other options, see `python -m pytest -h`
|
|
|
|
## Submitting Exercises
|
|
|
|
Note that, when trying to submit an exercise, make sure the solution is in the `$EXERCISM_WORKSPACE/python/scrabble-score` directory.
|
|
|
|
You can find your Exercism workspace by running `exercism debug` and looking for the line that starts with `Workspace`.
|
|
|
|
For more detailed information about running tests, code style and linting,
|
|
please see [Running the Tests](http://exercism.io/tracks/python/tests).
