计算两点之间的距离作为圆的半径然后使用 python class 计算面积和周长

Question

我一直在研究我的代码，编写了公式，但需要帮助重新组织以按预期执行 python 代码。

用户输入为一对坐标，
代码计算出的距离公式又是圆的半径，
然后我将根据输入的点坐标计算圆的 (a) 面积和 (b) 周长。

我在 class 圈中定义了我的公式。需要帮助重写下面的整个代码才能工作。现在只有输入有效。

import math

class Circle():
    def __init__(self, r, a, p):
        self.radius = r
        self.area = a
        self.perimeter = p
    
    def point_distance(x1, y1, x2, y2):
        r = math.sqrt(((y2-y1)**2) + ((x2-x1)**2))
        return r
    
    def area(self):
        a = 2*math.pi*self.radius**2
        return a
    
    def perimeter(self):
        return 2*self.radius*3.14

    x1, y1 = input("Enter the coordinates of the center of the circle (x, y): ").split(',')
    x2, y2 = input("Enter the coordinates of the point on the circle (x, y): ").split(',')
        
    x1,y1 = int(x1), int(y1)
    x2,y2 = int(x2), int(y2)
    
   # distance = math.sqrt((y2-y1)**2) + ((x2-x1)**2)
    print(f"The radius of the circle is {point_distance(x1, y1, x2, y2):.2f}")

## the code is not returning anything. Only the input works.

你试过了吗

import math

class Circle():
    def point_distance(x1, y1, x2, y2):
        r = math.sqrt((y2-y1)**2 + (x2-x1)**2)
        return r
        
    def area_calc(r):
        a = 2*math.pi*r**2
        return a
        
    def perimeter_calc(r):
        p = 2*r*3.14
        return p


############
def main():
    x1, y1 = input("Enter the coordinates of the center of the circle (x, y): ").split(',')
    x2, y2 = input("Enter the coordinates of the point on the circle (x, y): ").split(',')
        
    x1,y1 = int(x1), int(y1)
    x2,y2 = int(x2), int(y2)

    radius = Circle.point_distance(x1, y1, x2, y2)
    area = Circle.area_calc(radius)
    perimeter = Circle.perimeter_calc(radius)
    print("Radius :", radius)
    print("Area :", area)
    print("Perimeter :", perimeter)

if __name__ == "__main__":
    main()

Output:
Enter the coordinates of the center of the circle (x, y): 1,2
Enter the coordinates of the point on the circle (x, y): 3,4
Radius : 2.8284271247461903
Area : 50.265482457436704
Perimeter : 17.762522343406076
