cool Kata,
took me some time to finde the "and" in the "defeated"section.

thx for a great time

so i solved it with chaning all the calulated values into int()

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

35 characters min, here too... Walrus didn't helped too much... :)

There must be a Pythonic trick I've missed

indent can be 1 space too. but for this to works, you need one line!

The return plus the whitespace are 7 characters, the definition header takes 11 characters. The len call is 6 characters and the Walus Operator plus parentheses are 4 characters. So that's 31-7-11-6-4 = 3 characters for the computation.
Among which a multiply sign, the integer variable and the assigned length variable so 0 characters are left for the comparison operator...
Did I miss something?

You can omit return at all. Search about it on google.

Yes.

The indentation is 4 characters lost so everything needs to be in one line, isn't it?
