Hi,

• the Basic test case isn't doing what's it's announcing at all => the message should be something along the line of Check using a generator based coroutine.
• Why the rounding? I think there is only one way to do the correct computations here, right?

Cheers

You don't explain restrictions in the description, and missing tag: restricted

As I know, there are two types of coroutines on Python:

• Coroutines via Enhanced Generators
• Coroutines via Async (async/await)

You said about second one.
But, for example, there is PEP-342 about first one:
https://peps.python.org/pep-0342/

Sure, you can use it with OOP. But the main idea is solving it with coroutine. (I guess, I will limit it).

Coroutine in Python means a completely different thing than what is wanted from the kata:

https://docs.python.org/3/library/asyncio-task.html

Note that the word "couroutine" used by GeeksforGeeks is a term misuse: it's just a fancier generator.

Also, as some solutions shows, you don't even need a generator. Just an object will work.

• No random tests
