Top solutions require python 2.x.
I've had the same issue.

What an ingenious way!!!

It doesnt match test case but matches attempt, could you check whats wrong? I'm not really experienced in postgresql, just learning by katas

For example: what if there is 3.25 in tests? My solution is the same, but I think it is pretty cheating and should not be allowed. Hovewer top solutions for this kata does not work now also.

How do you do it without return statement?

I have 34 characters without 'return' in one line. can somebody help me?

Now I have 35 characters. Was used python golfing and walrus. Can somoeone help me? I think, the trouble in return statement.

At 34 without the whitespace after the return statement

@sinisake apparently the return statement is eating the extra characters
