# Help
|
||||
|
||||
## Running the tests
|
||||
|
||||
We use [pytest][pytest: Getting Started Guide] as our website test runner.
|
||||
You will need to install `pytest` on your development machine if you want to run tests for the Python track locally.
|
||||
You should also install the following `pytest` plugins:
|
||||
|
||||
- [pytest-cache][pytest-cache]
|
||||
- [pytest-subtests][pytest-subtests]
|
||||
|
||||
Extended information can be found in our website [Python testing guide][Python track tests page].
|
||||
|
||||
|
||||
### Running Tests
|
||||
|
||||
To run the included tests, navigate to the folder where the exercise is stored using `cd` in your terminal (_replace `{exercise-folder-location}` below with your path_).
|
||||
Test files usually end in `_test.py`, and are the same tests that run on the website when a solution is uploaded.
|
||||
|
||||
Linux/MacOS
|
||||
```bash
|
||||
$ cd {path/to/exercise-folder-location}
|
||||
```
|
||||
|
||||
Windows
|
||||
```powershell
|
||||
PS C:\Users\foobar> cd {path\to\exercise-folder-location}
|
||||
```
|
||||
|
||||
<br>
|
||||
|
||||
Next, run the `pytest` command in your terminal, replacing `{exercise_test.py}` with the name of the test file:
|
||||
|
||||
Linux/MacOS
|
||||
```bash
|
||||
$ python3 -m pytest -o markers=task {exercise_test.py}
|
||||
==================== 7 passed in 0.08s ====================
|
||||
```
|
||||
|
||||
Windows
|
||||
```powershell
|
||||
PS C:\Users\foobar> py -m pytest -o markers=task {exercise_test.py}
|
||||
==================== 7 passed in 0.08s ====================
|
||||
```
|
||||
|
||||
|
||||
### Common options
|
||||
- `-o` : override default `pytest.ini` (_you can use this to avoid marker warnings_)
|
||||
- `-v` : enable verbose output.
|
||||
- `-x` : stop running tests on first failure.
|
||||
- `--ff` : run failures from previous test before running other test cases.
|
||||
|
||||
For additional options, use `python3 -m pytest -h` or `py -m pytest -h`.
|
||||
|
||||
|
||||
### Fixing warnings
|
||||
|
||||
If you do not use `pytest -o markers=task` when invoking `pytest`, you might receive a `PytestUnknownMarkWarning` for tests that use our new syntax:
|
||||
|
||||
```bash
|
||||
PytestUnknownMarkWarning: Unknown pytest.mark.task - is this a typo? You can register custom marks to avoid this warning - for details, see https://docs.pytest.org/en/stable/mark.html
|
||||
```
|
||||
|
||||
To avoid typing `pytest -o markers=task` for every test you run, you can use a `pytest.ini` configuration file.
|
||||
We have made one that can be downloaded from the top level of the Python track directory: [pytest.ini][pytest.ini].
|
||||
|
||||
You can also create your own `pytest.ini` file with the following content:
|
||||
|
||||
```ini
|
||||
[pytest]
|
||||
markers =
|
||||
task: A concept exercise task.
|
||||
```
|
||||
|
||||
Placing the `pytest.ini` file in the _root_ or _working_ directory for your Python track exercises will register the marks and stop the warnings.
|
||||
More information on pytest marks can be found in the `pytest` documentation on [marking test functions][pytest: marking test functions with attributes] and the `pytest` documentation on [working with custom markers][pytest: working with custom markers].
|
||||
|
||||
Information on customizing pytest configurations can be found in the `pytest` documentation on [configuration file formats][pytest: configuration file formats].
|
||||
|
||||
|
||||
### Extending your IDE or Code Editor
|
||||
|
||||
Many IDEs and code editors have built-in support for using `pytest` and other code quality tools.
|
||||
Some community-sourced options can be found on our [Python track tools page][Python track tools page].

## Submitting your solution
|
||||
|
||||
You can submit your solution using the `exercism submit pig_latin.py` command.
|
||||
This command will upload your solution to the Exercism website and print the solution page's URL.
|
||||
|
||||
It's possible to submit an incomplete solution which allows you to:
|
||||
|
||||
- See how others have completed the exercise
|
||||
- Request help from a mentor
|
||||
|
||||

# Pig Latin
|
||||
|
||||
Welcome to Pig Latin on Exercism's Python Track.
|
||||
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||||
|
||||
## Introduction
|
||||
|
||||
Your parents have challenged you and your sibling to a game of two-on-two basketball.
|
||||
Confident they'll win, they let you score the first couple of points, but then start taking over the game.
|
||||
Needing a little boost, you start speaking in [Pig Latin][pig-latin], which is a made-up children's language that's difficult for non-children to understand.
|
||||
This will give you the edge to prevail over your parents!
|
||||
|
||||
[pig-latin]: https://en.wikipedia.org/wiki/Pig_latin
|
||||
|
||||
## Instructions
|
||||
|
||||
Your task is to translate text from English to Pig Latin.
|
||||
The translation is defined using four rules, which look at the pattern of vowels and consonants at the beginning of a word.
|
||||
These rules look at each word's use of vowels and consonants:
|
||||
|
||||
- vowels: the letters `a`, `e`, `i`, `o`, and `u`
|
||||
- consonants: the other 21 letters of the English alphabet
|
||||
|
||||
## Rule 1
|
||||
|
||||
If a word begins with a vowel, or starts with `"xr"` or `"yt"`, add an `"ay"` sound to the end of the word.
|
||||
|
||||
For example:
|
||||
|
||||
- `"apple"` -> `"appleay"` (starts with vowel)
|
||||
- `"xray"` -> `"xrayay"` (starts with `"xr"`)
|
||||
- `"yttria"` -> `"yttriaay"` (starts with `"yt"`)
|
||||
|
||||
## Rule 2
|
||||
|
||||
If a word begins with one or more consonants, first move those consonants to the end of the word and then add an `"ay"` sound to the end of the word.
|
||||
|
||||
For example:
|
||||
|
||||
- `"pig"` -> `"igp"` -> `"igpay"` (starts with single consonant)
|
||||
- `"chair"` -> `"airch"` -> `"airchay"` (starts with multiple consonants)
|
||||
- `"thrush"` -> `"ushthr"` -> `"ushthray"` (starts with multiple consonants)
|
||||
|
||||
## Rule 3
|
||||
|
||||
If a word starts with zero or more consonants followed by `"qu"`, first move those consonants (if any) and the `"qu"` part to the end of the word, and then add an `"ay"` sound to the end of the word.
|
||||
|
||||
For example:
|
||||
|
||||
- `"quick"` -> `"ickqu"` -> `"ickquay"` (starts with `"qu"`, no preceding consonants)
|
||||
- `"square"` -> `"aresqu"` -> `"aresquay"` (starts with one consonant followed by `"qu`")
|
||||
|
||||
## Rule 4
|
||||
|
||||
If a word starts with one or more consonants followed by `"y"`, first move the consonants preceding the `"y"`to the end of the word, and then add an `"ay"` sound to the end of the word.
|
||||
|
||||
Some examples:
|
||||
|
||||
- `"my"` -> `"ym"` -> `"ymay"` (starts with single consonant followed by `"y"`)
|
||||
- `"rhythm"` -> `"ythmrh"` -> `"ythmrhay"` (starts with multiple consonants followed by `"y"`)
