最近将在pip网站上发布triangle_area_calculators库（我编写的python第三方库）

triangle_area_calculators库用于计算不同类型及不同已知量的三角形面积

在triangle_area_calculators库中，有一个名为TriangleAreaCalculators的类

可以通过from triangle_area_calculators import TriangleAreaCalculators方式引用

 

 

import math

class TriangleAreaCalculators:
    HALF = 0.5

    @staticmethod
    def area_by_base_height(base, height):
        return TriangleAreaCalculators.HALF * base * height

        p = (a + b + c) / 2
        return math.sqrt(p * (p - a) * (p - b) * (p - c))

    @staticmethod
    def area_by_two_sides_angle(a, b, gamma_degrees):
        gamma_radians = math.radians(gamma_degrees)
        return TriangleAreaCalculators.HALF * a * b * math.sin(gamma_radians)

    @staticmethod

        return TriangleAreaCalculators.HALF * abs(x1 * (y2 - y3) + x2 * (y3 - y1) + x3 * (y1 - y2))

    @staticmethod

        theta_radians = math.acos(a / c)
        return TriangleAreaCalculators.HALF * a * c * math.sin(theta_radians)

    @staticmethod
    def area_of_equilateral_triangle(a):
        return (math.sqrt(3) / 4) * a ** 2
