Python Sympy Line.is_parallel()方法

在Sympy中，函数is_parallel()是用来检查两个线性实体是否平行的。

语法: Line.is_parallel(l2)

参数 :
l1: LinearEntity
l2: LinearEntity

返回:
True: 如果l1和l2是平行的。
False: 否则返回False.

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
