# Python | Sympy Line.intersection() method

• Last Updated : 10 Feb, 2020
In Sympy, the function `intersection()` is used to find the intersection with another geometrical entity.
```Syntax: Line.intersection(o)

Parameters:
o: Point or LinearEntity

Returns:
intersection: list of geometrical entities
```

Example #1:

 `# import sympy and Point, Line``from` `sympy ``import` `Point, Line`` ` `p1, p2, p3 ``=` `Point(``0``, ``0``), Point(``1``, ``1``), Point(``7``, ``7``)``l1 ``=` `Line(p1, p2)`` ` `# using intersection() method``showIntersection ``=` `l1.intersection(p3)`` ` `print``(showIntersection)`

Output:

`[Point2D(7, 7)]`

Example #2:

 `# import sympy and Point, Line, Segment``from` `sympy ``import` `Point, Line, Segment`` ` `p1, p2, p3, p4 ``=` `Point(``0``, ``0``), Point(``1``, ``1``), Point(``0``, ``5``), Point(``2``, ``6``)``l1 ``=` `Line(p1, p2)``s1 ``=` `Segment(p3, p4)`` ` ` ` `# using intersection() method``showIntersection ``=` `l1.intersection(s1)`` ` `print``(showIntersection)`

Output:

`[]`
