Python | Sympy line.parallel_line 方法
原文:https://www.geesforgeks.org/python-sympy-line-parallel_line-method/
在 Sympy 中，函数 parallel_line()用于创建一条平行于给定线性实体的新直线，该直线穿过给定点 p.
Syntax: Line.parallel_line(p)
Parameters:
p: Point
Returns: Line
示例#1:
蟒蛇 3
# import sympy and Point, Line
from sympy import Point, Line
p1, p2, p3 = Point(0, 0), Point(2, 3), Point(-2, 2)
l1 = Line(p1, p2)
# using parallel_line() method
l2 = l1.parallel_line(p3)
# checking l2 is parallel to l1 using is_parallel() method
isParallel = l1.is_parallel(l2)
print(isParallel)
输出:
True
例 2:
蟒蛇 3
# import sympy and Point3D, Line3D
from sympy import Point3D, Line3D
p1, p2, p3 = Point3D(0, 0, 0), Point3D(2, 3, 4), Point3D(-2, 2, 0)
l1 = Line3D(p1, p2)
# using parallel_line() method
l2 = l1.parallel_line(p3)
# checking l2 is parallel to l1 using is_parallel() method
isParallel = l2 = l1.is_parallel(p3)
print(isParallel)
输出:
True
