Area of a Convex Polygon
There is a convex polygon on a coordinate plane. This polygon is presented as a list of vertices coordinates. Each vertex is connected sequentially with the last connecting back to the first. A polygon has N vertices. You should write a program that will calculate the area of a polygon. The result should be given with one digits precision as ±0.1.
Input: Coordinates as a list of lists. Each list contains two integers.
Output: The area of the polygon as a float.
Example:
checkio([[1, 1], [9, 9], [9, 1]]) == 32 checkio([[4,...

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
