Python | Sympy Line.is_parallel() method Last Updated : 10 Feb, 2020 Improve Improve Like Article Like Save Share Report In Sympy, the function is_parallel() is used to check whether the two linear entities are parallel or not. Syntax: Line.is_parallel(l2) Parameters: l1: LinearEntity l2: LinearEntity Returns: True: if l1 and l2 are parallel, False: otherwise. Example #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) Output: True Example #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) Output: False Like Article Suggest improvement Next Python | Sympy Line.parallel_line method Share your thoughts in the comments Add Your Comment Please Login to comment...
