Python| Sympy Line.parallel_line 方法

在 Sympy 中，函数parallel_line() 用于创建一条与给定线性实体平行的新线，该线通过给定点 p。

Syntax: Line.parallel_line(p)

Parameters:
p: Point

Returns: Line

示例 #1：

Python3

# 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

示例 #2：

Python3

# 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
