问题 Right now, I am at the starting point of a project in which I am supposed to compare two words semantically. I came to know about WordNet wherein we find distance between words to find how similar they are in terms of their meaning. It would be really helpful if you can suggest some more techniques and which method would be the best one. 来源： https://stackoverflow.com/questions/18570378/what-are-the-different-techniques-for-comparing-2-words-semantically-which-one

问题 This is an algorithm in python to validate a day entry. I want to know what does that mean exactly the expression "if day" (semantics). I only know the effect of "if" on boolean expressions not on variables like integers or arrays (I've seen some). Does anyone have an explanation? def valid_day(day): if day and day.isdigit():#if day day = int(day) if day > 0 and day <= 31: return day 回答1: in python, writing if var: has the same effect as writing if bool(var): (where bool is the built-in bool

问题 The span element seems to be exactly like a div, but at the in-line level rather than at the block level. However, I can't seem to think of any beneficial logical divisions that the span element can provide. A single sentence, or word if not contained in a sentence, seems to be the smallest logical part. Ignoring CSS, since CSS is only for layout and not for semantic meaning, when does span provide additional semantic value by chopping up a sentence or string of words ? It seems that in all

问题 Tuple elements may have side-effects, and some of them may depend on others. Consider this program: fn main() { let mut v = vec![1, 2]; match (v.pop(), v.pop()) { (Some(z), Some(y)) => println!("y = {}, z = {}", y, z), _ => unreachable!(), } } Does it output y = 1, z = 2 or y = 2, z = 1 ? A few rounds on the Rust Playground suggests the former on stable 1.32.0, but maybe it would change if I ran it more times, recompiled the compiler, changed compiler versions, etc. Is there a documented
