Scrabble game score calculator

In the Scrabble game, each letter has scores associated with them. The total score of a word is the sum of its letter scores. The most common letters are worth less points, while the less common letters are worth more points. We are going to use a dictionary that maps from letters to point values. The points associated with each letter are shown below:

points = "A": 1, "B": 3, "C": 3, "D": 2, "E": 1, "F": 4, "G": 2, "H": 4, "I": 1, "J": 2, "K": 5, "L": 1, "M": 3, "N": 1, "O": 1, "P": 3, "Q": 10, "R": 1, "S": 1, "T": 1, "U": 1, "V": 4, "W": 4, "X": 8, "Y": 4, "Z": 10

Write a function that calculates and displays the Scrabble score for a given word. Use the dictionary to calculate the score.

The Scrabble board includes some cells that multiply the value of a letter or the value of a whole word. We will ignore these squares in this exercise.

Write pytests to test your function, for example for the following test cases:

**testcase number**   |**input**                |  **expected output**
-----------------| ---------------------- |-----------------
1                | `''`                  | 0
2                | `'Hello!'`            | 8
3                | `'zzz'`               | 30
4                | `'Surprise'`          | 10
5                | `'1234'`              | 0
6                | `'And with spaces?'`  | 24
