直角坐标的三角形

Question

我是新手。谁能帮我。

class Triangle():
    def __init__(self, a, b, c):
        """
        Constructor for Vec4
        Expects points as arrays in the form of [x, y].
        All coordinates are given as cartesian coordinates.
        """
        self.a = a
        self.b = b
        self.c = c


    def __str__(self):
        """
        Returns a string representation of the triangle. The string is formatted as follows:

        Point A: 0.00 0.00
        Point B: 0.00 0.00
        Point C: 0.00 0.00

        """
        return ""

Answer 1

您需要提出一个具体问题。查看这些guidelines。

Answer 2

这是我的实现以及如何实现。您可以返回字符串，并记住将整数转换为字符串。

class Triangle():
    def __init__(self, a, b, c):
        """
        Constructor for Vec4
        Expects points as arrays in the form of [x, y].
        All coordinates are given as cartesian coordinates.
        """
        self.a = a
        self.b = b
        self.c = c


    def __str__(self):
        """
        Returns a string representation of the triangle. The string is formatted as follows:

        Point A: 0.00 0.00
        Point B: 0.00 0.00
        Point C: 0.00 0.00

        """
        return "Point A: " + str(self.a[0]) + " " + str(self.a[1]) + "\nPoint B: " + str(self.b[0]) + " " + str(self.b[1]) + "\nPoint C: " + str(self.c[0]) + " " + str(self.c[1])

t = Triangle([5,4], [1,2], [7,9])
print(t)

输出：
Point A: 5 4
Point B: 1 2
Point C: 7 9

Answer 3

假设点是一个类似（1.5，6.7）的元组

这里是代码：

class Triangle():
def __init__(self, a, b, c):
    """
    Constructor for Vec4
    Expects points as arrays in the form of [x, y].
    All coordinates are given as cartesian coordinates.
    """
    self.a = a
    self.b = b
    self.c = c


def __str__(self):
    """
    Returns a string representation of the triangle. The string is formatted as follows:

    Point A: 0.00 0.00
    Point B: 0.00 0.00
    Point C: 0.00 0.00

    """
    return f"Point A: {self.a[0]} {self.a[1]}\nPoint B: {self.b[0]} {self.b[1]}\nPoint C: {self.c[0]} {self.c[1]}"

您可以使用以下方法来检查：
t = Triangle((2.34,4.62), (6.7,8.52), (9.34,3.32))
print(t)
