@PVMPATCH Python doesn't support adding strings and integers directly. It would raise an error. You have to cast it first. It's a feature of the language. Please read that whole section of the documentation you linked. It's explaining how Python works, and how type annotations and tools can help you detect bugs in your code like that one and fix it. |
