Import math sqrt
WitrynaThat’s all it takes! You can now use math.sqrt() to calculate square roots.. sqrt() has a straightforward interface. It takes one parameter, x, which (as you saw before) stands for the square for which you are trying to calculate the square root.In the example from earlier, this would be 25.. The return value of sqrt() is the square root of x, as a … Witryna13 mar 2024 · 在 Python 中，可以使用下面的代码实现 (x-h)² + (y-k)² = r² : ```python import math def is_point_in_circle(x, y, h, k, r): return math.sqrt((x-h)**2 + (y-k)**2) <= r ``` 在这段代码中，函数 `is_point_in_circle(x, y, h, k, r)` 接受五个参数：x 和 y 是待测点的坐标，h 和 k 是圆心的坐标，r 是圆的半径。
