[/edit] removed silly reply
[/edit2] I think your position logic is faulty; position[0] is 3 (not 0), position[-3] is 0 so the answer is correct but your logic states position[-2]. This might be confusion on zero- or one-based counting? Is it obvious I chose the wrong answer?
Thank you for the challenge!

the answer for val2[-3] is 3, and -3 is not equal to -2

Agreed the indexing logic isn't right. Negative values index backwards from the end of the string (-1 being the last character, etc.) In this case, the index of 0 and -4 are the same character (3), etc, so it would look like so:
3 0 . 0
0 1 2 3 (positive index numbers)
-4 -3 -2 -1 (negative index numbers)
I got the answer wrong, but then I looked into it because I was curious to understand it. I'm a bit of a newbie with Python so I ran some different strings through this code in my interpreter to make sure I understood it.
Regardless, thanks for the cool exercise.

Python newbie here. Why is the value of val1 (and val2) 30.0 and not just 30?

The radicand is floating point so the result will also be. Rounding the floating point result will remain floating point.
