问题 I'm trying to create an IF Statement on Sheets so that if at least one of the last 3 columns (W,X,Y) contains 'YES' then column Z will say 1. If all of them are empty or contain 'NO' then column Z will say 'FALSE' or 'NO'. Please see what I have below, each time I do it, it only takes the data from W and ignores X and Y. =IF(W3='DATA VALIDATION'!B2, 1, AND(X3='DATA VALIDATION'!B2,1,AND(Y3='DATA VALIDATION'!B2,1,)) ) 回答1: Use a countif across W:Y to see if there is a Yes . Any result greater

问题 This question already has answers here : How do the PHP equality (== double equals) and identity (=== triple equals) comparison operators differ? (21 answers) Closed 6 years ago . In my case should I use != as below, or is !== more appropriate, what is the difference. private function authenticateApi($ip,$sentKey) { $mediaServerIp = '62.80.198.226'; $mediaServerKey = '45d6ft7y8u8rf'; if ($ip != $mediaServerIp ) { return false } elseif ($sentKey != $mediaServerKey ) { return false } else {

问题 I am working with a legacy code base written in VB and have run into a conditional operator that I don't understand and cannot figure out what to search for to resolve it. What I am dealing with is the following code and the variables that result as true. The specific parts that I do not understand are (1) the relationship between the first X and the first parens (-2 and (2) the role of X < 2 If X is a value below -2 it evaluates as false . If X is a value above 2 it evaluates as true . If Y

问题 I want to understand slicing with timeseries in Pandas and I am looking at the possibility of combining in a logical statement (combining and , or, not operands) conditions involving dates. So this is a reproducible example: HAO_10 Date Price 2018-01-02 30.240000 2018-01-03 30.629999 2018-01-04 30.860001 2018-01-05 31.010000 2018-01-08 31.389999 2018-01-09 31.309999 2018-01-10 31.400000 2018-01-11 31.580000 2018-01-12 31.680000 2018-01-16 31.200001 HAO_10.iloc[((HAO_10.index < datetime

问题 How can i check whether a sentence contain combinations? For example consider sentence. John appointed as new CEO for google. I need to write a rule to check whether sentence contains < 'new' + 'Jobtitle' >. How can i achieve this. I tried following. I need to check is there 'new' before word . Rule: CustomRules ( { Sentence contains {Lookup.majorType == "organization"}, Sentence contains {Lookup.majorType == "jobtitle"}, Sentence contains {Lookup.majorType == "person_first"} } ) 回答1: One way

问题 Suppose I have a matrix A which is (m x n) and a vector B which is (m x 1) . This vector B is a vector of zeros and ones. Also let the scalar s be the sum of the elements in B . I want to create a matrix C which is s x n corresponding to the rows of B which equal 1, and a vector D which is s x 1, with the position of those elements in A . Take as an example: A = [1, 2, 3; 4, 5, 6; 7, 8, 9; 10, 11, 12; 13, 14, 15 ] B = [0; 1; 0; 1; 1] Then: C = [ 4, 5, 6; 10, 11, 12; 13, 14, 15 ] and D = [2; 4

问题 JavaScript has assignment operators corresponding to arithmetic ones: += , -= , *= , /= , %= . JavaScript also has assignment operators corresponding to bitwise ones: <<= , >>= , >>>= , &= , ^= , |= . But it doesn't have assignment operators corresponding to logical ones: ||= , &&= . Then, I can't do things like aVeryLongVariableIdontWantToRepeat ||= 1; In this other question it's explained why JS Java doesn't have such operators. I guess it's the same for JS. But I want to know if there is a

问题 I'm having a hard time writing up what seems should be a simple if statement! I need it to say if mod does not equal a, b, or c - then do this. Here is what I was trying but have been unsuccessful: var mod = CURRENT_MODULE_ID; if (mod != "5827289" && mod != "5195103" && mod != "5181422") { doSomething(); } When I type this into my editor it says there is an error, specifically that "The entity name must immediately follow the '&' in the entity reference." .. and is not working when I go to

问题 I have a table to lookup a value like this: logical test | points -------------|------- <= 0 | 1 <= 10 | 2 <= 20 | 4 > 20 | 5 If my cell is (A1 for example) <= 0 the result is 1... if my cell is <=10 the result is 2 ... if my cell is > 20 the result is 5. I could use several if functions for that, but I want to prevent the user to have to change the formula if the table changes. For example, if, for some reason, the first line changes to > 0 it wouldn't be necessary to change the formula. I

问题 I have often used the following construct in Javascript: var foo = other_var || "default_value"; In Javascript, if the left side is falsy, then the value on the right side is assigned. It is very handy, and saves writing longer and unnecessarily explicit ternary expressions. Is there a name for this sort of construct ? Bonus: Is there a trick to do this in Php without using a ternary operator? PS: another variant is to throw an error if you don't get a truthy value, instead of giving a
