Searchlights Searchlights

How many vertices of the regular polygons can you see in the light?

You are given two lists as input values (a list of the regular polygons and a list of the circles.)

Detail of the regular polygon (as a tuple of 4 integers):

  • x coordinate of the top vertex.
  • y coordinate of the top vertex.
  • The length of an edge.
  • The number of vertices.

Detail of the circle (as a tuple of 3 integers):

  • x coordinate of the center.
  • y coordinate of the center.
  • The length of the radius.

You have to return the number of vertices in the circles.


  • The Regular polygons is vertical symmetry.
  • Don't count vertices with negative coordinates. (e.g. (-1, 2), (2, -3), (-3, -4))
  • No test case where the circumference is close to the vertices.


searchlights([(2, 3, 2, 3)], [(1, 2, 1)]) == 1 # regular triangle
searchlights([(4, 5, 2, 4)], [(4, 4, 3)]) == 4 # square

Input: two arguments:

  • The regular polygons (a list of tuples of 4 integers)
  • The circles (a list of tuples of 3 integers)

Output: The number of vertices (an integer).


  • length of edge ≥ 1
  • length of radius ≥ 1
  • Regular polygons doesn't have any common vertex.

How it is used: To draw a regular polygon.

CheckiO Extensions

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.

In order to install CheckiO client you'll need installed Python (version at least 3.8)

Install CheckiO Client first:

pip3 install checkio_client

Configure your tool

checkio --domain=py config --key=

Sync solutions into your local folder

checkio sync

(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)

checkio serv -d

Alternatevly, you can install Chrome extension or FF addon

checkio install-plugin
checkio install-plugin --ff
checkio install-plugin --chromium

Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
