问题 I am trying to filter a large dictionary based on values from another dictionary. I want to store the keys to filter on in a list. So far I have: feature_list = ['a', 'b', 'c'] match_dict = {'a': 1, 'b': 2, 'c': 3} all_dict = {'id1': {'a': 1, 'b': 2, 'c': 3}, 'id2': {'a': 1, 'b': 4, 'c': 3}, 'id3': {'a': 2, 'b': 5, 'c': 3}} filtered_dict = {k: v for k, v in all_dict.items() for feature in feature_list if v[feature] == match_dict[feature]} This returns all the ids because I think the if

问题 I am trying to write the equivalent of an if statement with SSE intrinsics. I am using __m128 _mm_cmplt_ps(__m128 a, __m128 b) to do the comparison a < b, and this returns 0xffffffff or 0x0 if the comparison was respectively true or false. I would like to convert these values into 1 and 0. In order to do this, is it correct to implement the logical "and" __m128 _mm_and_ps(__m128 c , __m128 d) , where c is the result of the conversion and d is, e.g., 0xffffffff ? Thank you for your attention.

问题 I have question about Cypress. I have an element on page which doesn't appear allways. There is no logic when it shows and when not. Is in Cypress some IF/THEN function or something how do you check if the element is displayed (so fill it up) and when you don't see it than skip that step? My code: if (Cypress.$('[data-bind="validationElement: interestInsurable"]').length > 0) { cy.get('[for="p4-conditional-csob-interest-insurable-1"]').click() } else {cy.get('#car-info-serie')} This is how it

问题 In a Python Pandas DataFrame , I'm trying to apply a specific label to a row if a 'Search terms' column contains any possible strings from a joined, pipe-delimited list. How can I do conditional if, elif, else statements with Pandas? For example: df = pd.DataFrame({'Search term': pd.Series(['awesomebrand inc', 'guy boots', 'ectoplasm'])}) brand_terms = ['awesomebrand', 'awesome brand'] footwear_terms = ['shoes', 'boots', 'sandals'] #Note: this does not work if df['Search term'].str.contains('

问题 say you have (any amount) values in an array and you want to see if any of them is over (lower amount) and under higher amount, how would you do that? answer without doing a for loop or any lengthy code. Maybe something like: var havingParty = false; if ((theArrayWithValuesIn > 10) && (theArrayWithValuesIn < 100)) { havingParty = true; } else { havingParty = false; } would work. Please note: x and y , collision detection, compact code. 回答1: If I understand your question correctly, you want to

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 This will mostly get duplicated but I sincerely don't know how to search this question since it is too long and complicated. Sorry in advance! Back to the problem, let's say I take an input from the user with the Scanner class. Imagine that Scanner is imported and everything is set. Scanner scan = new Scanner(); String input = scan.nextLine(); switch( input) { case "attack": System.out.println( "You attacked the enemy!"); break; case "defend": System.out.println( "You blocked the enemy!");
