Thanks for catching the typo. Fixed.

No, see issue above.

Done.

The original design of this kata was in Ruby. That design maybe hasn't translated to other languages as cleanly. I don't know Python so I can't really say if the translation used could have been done better, but for this kata having slight variations in the design per language probably is necessary.

I face the same issue. Can author explain this behavior?

thanks. Python is not my first language. So I am still learning... a lot.

this should be fixed now. I put the reference functions into the describe block. Please re-check that the tests are now in the proper form.

fixed

Oh dear, looks like this kind of scribbles a mad scientist does in movies.

Hi, I just join and see the solutions after I submit that one, and I used the way you say because I was first ask to help on this problem as a math problem (no computer) before the student told me it was for this website.
Mine is longer because I am a full beginner in Python and didn't know about join or enumerate, and just tried to make it simple.
Now, looking at the others solutions, I only see as marked "clever" very short solutions (in lines of code) and before I saw your comment I didn't even see your solution.

Do not use intermediate floats. Closing.

Indeed, nice kata.
