# Help

3+
## Running the tests
4+
5+
We use [pytest][pytest: Getting Started Guide] as our website test runner.
6+
You will need to install `pytest` on your development machine if you want to run tests for the Python track locally.
7+
You should also install the following `pytest` plugins:
8+
9+
- [pytest-cache][pytest-cache]
10+
- [pytest-subtests][pytest-subtests]
11+
12+
Extended information can be found in our website [Python testing guide][Python track tests page].
13+
14+
15+
### Running Tests
16+
17+
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_).
18+
Test files usually end in `_test.py`, and are the same tests that run on the website when a solution is uploaded.
19+
20+
Linux/MacOS
21+
```bash
22+
$ cd {path/to/exercise-folder-location}
23+
```
24+
25+
Windows
26+
```powershell
27+
PS C:\Users\foobar> cd {path\to\exercise-folder-location}
28+
```
29+
30+
<br>
31+
32+
Next, run the `pytest` command in your terminal, replacing `{exercise_test.py}` with the name of the test file:
33+
34+
Linux/MacOS
35+
```bash
36+
$ python3 -m pytest -o markers=task {exercise_test.py}
37+
==================== 7 passed in 0.08s ====================
38+
```
39+
40+
Windows
41+
```powershell
42+
PS C:\Users\foobar> py -m pytest -o markers=task {exercise_test.py}
43+
==================== 7 passed in 0.08s ====================
44+
```
45+
46+
47+
### Common options
48+
- `-o` : override default `pytest.ini` (_you can use this to avoid marker warnings_)
49+
- `-v` : enable verbose output.
50+
- `-x` : stop running tests on first failure.
51+
- `--ff` : run failures from previous test before running other test cases.
52+
53+
For additional options, use `python3 -m pytest -h` or `py -m pytest -h`.
54+
55+
56+
### Fixing warnings
57+
58+
If you do not use `pytest -o markers=task` when invoking `pytest`, you might receive a `PytestUnknownMarkWarning` for tests that use our new syntax:
59+
60+
```bash
61+
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
62+
```
63+
64+
To avoid typing `pytest -o markers=task` for every test you run, you can use a `pytest.ini` configuration file.
65+
We have made one that can be downloaded from the top level of the Python track directory: [pytest.ini][pytest.ini].
66+
67+
You can also create your own `pytest.ini` file with the following content:
68+
69+
```ini
70+
[pytest]
71+
markers =
72+
task: A concept exercise task.
73+
```
74+
75+
Placing the `pytest.ini` file in the _root_ or _working_ directory for your Python track exercises will register the marks and stop the warnings.
76+
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].
77+
78+
Information on customizing pytest configurations can be found in the `pytest` documentation on [configuration file formats][pytest: configuration file formats].
79+
80+
81+
### Extending your IDE or Code Editor
82+
83+
Many IDEs and code editors have built-in support for using `pytest` and other code quality tools.
84+
Some community-sourced options can be found on our [Python track tools page][Python track tools page].

## Submitting your solution
97+
98+
You can submit your solution using the `exercism submit darts.py` command.
99+
This command will upload your solution to the Exercism website and print the solution page's URL.
100+
101+
It's possible to submit an incomplete solution which allows you to:
102+
103+
- See how others have completed the exercise
104+
- Request help from a mentor
105+
106+

# Hints
2+
3+
## General
4+
5+
- This challenge is all about calculating if a point falls _on, in, or outside_ a given circle.
6+
- There are two different ways of calculating if a point falls on, in, or outside a circle.
7+
- This _Stack Overflow_ Post: [Equation for Testing if a Point is Inside a Circle][point-circle-equation] outlines one method.
8+
- This _DoubleRoot_ post [Position of a point relative to a circle][point-to-circle] outlines a different one.
9+
- This _Math is Fun_ post covers a more general [Distance Between 2 Points][distance-between-two-points] calculation.
10+
- Because the dart board is a set of _concentric_ circles, the order in which you calculate points could change the answer significantly.
11+
You should pay attention to which direction your calculations "move" in.
12+
- Remember that this exercise has many potential solutions and many paths you can take along the way.
13+
No path is manifestly "better" than another, although a particular path may be more interesting or better suited to what you want to learn or explore right now.
14+
- Some paths may trade speed for clarity.
15+
Others might take up more memory but be more scalable or maintainable.
16+
- We encourage you to try out more than one programming strategy to see what happens.

# Darts
2+
3+
Welcome to Darts on Exercism's Python Track.
4+
If you need help running the tests or submitting your code, check out `HELP.md`.
5+
If you get stuck on the exercise, check out `HINTS.md`, but try and solve it without using those first :)
6+

## Instructions
8+
9+
Calculate the points scored in a single toss of a Darts game.
10+
11+
[Darts][darts] is a game where players throw darts at a [target][darts-target].
12+
13+
In our particular instance of the game, the target rewards 4 different amounts of points, depending on where the dart lands:
14+
15+
![Our dart scoreboard with values from a complete miss to a bullseye](https://assets.exercism.org/images/exercises/darts/darts-scoreboard.svg)
16+
17+
- If the dart lands outside the target, player earns no points (0 points).
18+
- If the dart lands in the outer circle of the target, player earns 1 point.
19+
- If the dart lands in the middle circle of the target, player earns 5 points.
20+
- If the dart lands in the inner circle of the target, player earns 10 points.
21+
22+
The outer circle has a radius of 10 units (this is equivalent to the total radius for the entire target), the middle circle a radius of 5 units, and the inner circle a radius of 1.
23+
Of course, they are all centered at the same point — that is, the circles are [concentric][] defined by the coordinates (0, 0).
24+
25+
Given a point in the target (defined by its [Cartesian coordinates][cartesian-coordinates] `x` and `y`, where `x` and `y` are [real][real-numbers]), calculate the correct score earned by a dart landing at that point.
26+
