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:

`[]`
