Python| Sympy Line.is_parallel() 方法

在 Sympy 中，函数is_parallel()用于检查两个线性实体是否平行。

Syntax: Line.is_parallel(l2)

Parameters:
 l1: LinearEntity
 l2: LinearEntity

Returns:
 True: if l1 and l2 are parallel,
 False: otherwise.

示例 #1：

# import sympy and Point, Line
from sympy import Point, Line
  
p1, p2 = Point(0, 0), Point(1, 1)
p3, p4 = Point(3, 4), Point(6, 7)
  
l1, l2 = Line(p1, p2), Line(p3, p4)
  
# using is_parallel() method
isParallel = Line.is_parallel(l1, l2)
  
print(isParallel)

输出：

True

示例 #2：

# import sympy and Point, Line
from sympy import Point, Line
  
p1, p2 = Point(0, 0), Point(1, 1)
p3, p4 = Point(3, 4), Point(6, 6)
  
l1, l2 = Line(p1, p2), Line(p3, p4)
  
# using is_parallel() method
isParallel = Line.is_parallel(l1, l2)
  
print(isParallel)

输出：

False
