Simple Areas
Stephan works with simple forms when constructing something, and he need some programming tools to calculate his expenses. Let's take a trip back to our school days and pull out some simple geometry for this.
You should write a function to calculate the area of simple figures: circles, rectangles and triangles. You are give an arbitrary number of arguments and depending on this, the function calculates area for the different figures.

One argument  The diameter of a circle and you need calculate the area of the circle.

Two arguments  The side lengths of a rectangle and you need calculate the area of the rectangle.

Three arguments  The lengths of each side on a triangle and you need calculate the area of the triangle.
The result should be given with two digits precision as ±0.01.
Tips: Think about how to work with an arbitrary number of arguments .
Input: One, two or three arguments as floats or as integers.
Output: The area of the circle, the rectangle or the triangle as a float.
Example:
simple_areas(3) == 7.07 simple_areas(2, 2) == 4 simple_areas(2, 3) == 6 simple_areas(3, 5, 4) == 6 simple_areas(1.5, 2.5, 2) == 1.5
How it is used: Python can be an useful tool for mathematics and science. You can easily implement any formulas or math algorithm with this simple and readable programming language.
Precondition:
0 < len(args) ≤ 3
all(0 < x ≤ 1000 for x in args)
For "triangle" cases the sum of the lengths of any two sides always exceeds the length of the third side.
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 installplugin
checkio installplugin ff
checkio installplugin chromium
Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
