有没有Python模块或内置函数可以帮助我编写这个程序？

Question

我正在Exercism网站上做一个练习，我有点被困在如何开始这个练习上。我不想要任何详细的答案；我只是在寻找如何开始的正确方向。当给定一组（x，y）坐标时，我想知道是否有任何特定的Python模块、函数等可以帮助我找出该点在网格上的位置，特别是相对于网格上具有中心（0，0）的圆

我希望这是一个更具体一点，我正在寻找！我在编写程序时没有任何特别的问题（现在！），但我甚至不知道如何开始，因为我不确定是否需要从头开始编写一个函数来解决上述所有问题，或者Python是否已经有了一些东西可以帮助完成这项特殊任务

谢谢

Write a function that returns the earned points in a single toss of a Darts game.

Darts is a game where players throw darts to a target.

In our particular instance of the game, the target rewards with 4 different amounts of points, depending on where the dart lands:

If the dart lands outside the target, player earns no points (0 points).
If the dart lands in the outer circle of the target, player earns 1 point.
If the dart lands in the middle circle of the target, player earns 5 points.
If the dart lands in the inner circle of the target, player earns 10 points.
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. Of course, they are all centered to the same point (That is, the circles are concentric) defined by the coordinates (0, 0).

Write a function that given a point in the target (defined by its real cartesian coordinates x and y), returns the correct amount earned by a dart landing in that point.

一种方法是使用毕达哥拉斯定理来计算省道和中心之间的距离

r = math.sqrt(x*x+y*y)

这将给出省道和目标中心之间的距离
