Please explain where they are, as well as their solution.

Answer 1

can only concatenate str (not "int") to str

Answer 2

timeout=self.wait + 10
here, with the help of a plus sign, concatenation (combining strings) occurs, since one of the elements is taken as a string.
if we want to add, both terms must be digits.
let's do it like this:
timeout=int(self.wait) + 10
