For boolean arguments e.g. >> 7 and "" . Wouldn't this technically be both true? Since bool(7) and bool("") = True?

bool(7) True bool("") True 7 and "" ' '

Is it because they are two different data types?

Hi Peter. bool(7) and bool("") would actually be False. Remember with "and" all arguments have to be True for it to be True. While bool(7) is True, bool("") is empty so its False. And True and Flase is False. If you used "or" it would be True since with ors only one arguement has to be True for it to be True. 

bool(7) = True
bool("") = False
bool(7) and bool("")  = True and False = False
bool(7) or bool("")  = True or False = True
