> Python3 program which hasn't crashed at some point due to me mixing-up string/bytes Not sure what that even is, but I'd point out that dynamically-typed ≠ Python. In particular, the "hash languages" (Python, Ruby, JavaScript) seem to make it particularly easy to make a hash of things, but not due to the dynamic typing. I've never had that problem with NSString and NSData. They are quite distinct. > Python3 ... crunching numbers ... map instead of list ?? Why would you output a map when you are crunching numbers? To get a "list", for example, I'd use an NSArray. It seems tricky to get an NSDictionary instead, since you have to explicitly ask for an NSDictionary in order to get one.
