# ETL
|
||||
|
||||
Welcome to ETL on Exercism's Python Track.
|
||||
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||||
|
||||
## Introduction
|
||||
|
||||
You work for a company that makes an online multiplayer game called Lexiconia.
|
||||
|
||||
To play the game, each player is given 13 letters, which they must rearrange to create words.
|
||||
Different letters have different point values, since it's easier to create words with some letters than others.
|
||||
|
||||
The game was originally launched in English, but it is very popular, and now the company wants to expand to other languages as well.
|
||||
|
||||
Different languages need to support different point values for letters.
|
||||
The point values are determined by how often letters are used, compared to other letters in that language.
|
||||
|
||||
For example, the letter 'C' is quite common in English, and is only worth 3 points.
|
||||
But in Norwegian it's a very rare letter, and is worth 10 points.
|
||||
|
||||
To make it easier to add new languages, your team needs to change the way letters and their point values are stored in the game.
|
||||
|
||||
## Instructions
|
||||
|
||||
Your task is to change the data format of letters and their point values in the game.
|
||||
|
||||
Currently, letters are stored in groups based on their score, in a one-to-many mapping.
|
||||
|
||||
- 1 point: "A", "E", "I", "O", "U", "L", "N", "R", "S", "T",
|
||||
- 2 points: "D", "G",
|
||||
- 3 points: "B", "C", "M", "P",
|
||||
- 4 points: "F", "H", "V", "W", "Y",
|
||||
- 5 points: "K",
|
||||
- 8 points: "J", "X",
|
||||
- 10 points: "Q", "Z",
|
||||
|
||||
This needs to be changed to store each individual letter with its score in a one-to-one mapping.
|
||||
|
||||
- "a" is worth 1 point.
|
||||
- "b" is worth 3 points.
|
||||
- "c" is worth 3 points.
|
||||
- "d" is worth 2 points.
|
||||
- etc.
|
||||
|
||||
As part of this change, the team has also decided to change the letters to be lower-case rather than upper-case.

If you want to look at how the data was previously structured and how it needs to change, take a look at the examples in the test suite.
