Man, I'm annoyed. lol
I forgot to put quotations around Even and Odd......

Simple and clean

This is best one becouse work faster then others

But the solution requires you return an int, so if it overflows, no solution could do it correctly (your solution throws an exception)

Correct. In cases where operators are the same precedence, we also have to take into account the associativity to determine the order of evaluation.

A bit late, but doesn't it solve from left to right?

Why is that? Still learning...

although all the tests returned the right number

No, with print your function returned None.

But did your function return anything?

I used this same code but instead of return i put "print"
and although all the tests returned the right number, the exercise was marked down.
Anyone can explain why?

if out of range,it will be incorrect.
input 999999-->output -364189984
the correct will be output 0
