evaluate

问题 I have this list in a txt file: [1, "hello", {"Name": "Tom"}, [2, 3, "hello_hello"], (800, 600)] There are an int , a str , a dict , a list and a tuple (not that it was really the matter). I'd like to read this like this was a list (as it really is) not like one string. I'd like to get a result like: elem[0] = 1 elem[1] = "hello" elem[2] = {"Name": "Tom"} elem[3] = [2, 3, "hello_hello"] elem[4] = (800,600) Also it would be really nice if the dictionary evaluated eval() immediately, but that's

问题 I have an array structure of 60 elements. I'd like to use a for/foreach/while to read this structure. This is what I have : $this->details->field_link_01[0]['title'] $this->details->field_link_02[0]['title'] .. $this->details->field_link_60[0]['title'] And what i need is the following. $myvar = eval ( "$this->details->field_link_" . $cont . "[0]['title']" ) What I have seen is PHP let to use $ as evaluation function $myvar = ${"this->details->field_link_" . $cont . "[0]['title']" } But it

问题 I've been assigned to create a Java program which reads a string equation and calculates its value. But the code I've managed to create this far is only able to calculate single-digit integers. And I have no idea how to make my longer length integers work. What should my function look like in order to work with double or even triple digit integers? public class Ex8 { /** * @param args the command line arguments */ public static void main(String[] args) { // TODO code application logic here

问题 This should be fairly simple but I understand why it doesn't work. I am hoping there is a clever way to do the following: I have a string 'movieclip1.movieclip2' I have a container movieclip - Container. Now to evaluate the string normally I would look something like: this.container['movieclip']['movieclip2'] Because clip2 is a child of movieclip. But I would like to parse or evaluate the string with the dot syntax to read the string as a internal path. this.container[evaluatedpath]; // which

问题 I have javascipt string in LaTeX format. For example: \frac{y^2}{2}x-\frac{2}{\sqrt{y}}+2(x-y)^2 I want to be able evaluate it with defined variables. Does anyone know framework or lib for this purpose? I've tried to find it in google and stack but without success. If you suggest to evaluate it using replace/eval - please answer without evaluating example above. Do not waste your strength =) Sorry, if I duplicate someone question - I will be grateful for link. 回答1: I think you'd need to get

问题 I have this function working ( It returns the row where the text DK001 sits in the ID range) Found = Application.Evaluate("=IF(ID=""DK001"",ROW(ID),""x"")") I would like to feed the searchcriteria (e.g. DK001) as a string, like Found = Application.Evaluate("=IF(ID=SearchString,ROW(ID),""x"")") I fail in creating a string that is accepted as a search criteria. I need your help on this! What am I doing wrong? This Evaluate function is haunting me .... What if I now wanted to send a value (not a

问题 My VBA code is Function yEval(entry As String) yEval = Evaluate(entry) Application.Volatile End Function in Sheet1 in cell f4 i have formula =yEval(Sheet2!E19) cell d4 on sheet1 contains number 12 Sheet2!I19 contains string $Q if Sheet2!e19 has string INDIRECT("pries!"&Sheet2!I19&12) or INDIRECT("pries!"&Sheet2!I19&Sheet1!d4) or INDIRECT("pries!"&Sheet2!I19&"Sheet1!D"&row()+12) the formula return result from sheet pries!$Q12 if Sheet2!e19 has string INDIRECT("pries!"&Sheet2!I19&address(row()

问题 When I try to navigate the pagination on sites with links where href is a __doPostBack function call, I never achieve the page change. I am not sure what I am missing, so after a few hours of messing around I decided to see if someone here can give me a clue. This is my code (uber-simplified to show the use case). var casper = require('casper').create({ verbose: true, logLevel: "debug" }); casper.start('http://www.gallito.com.uy/inmuebles/venta'); // here i simulate the click on a link in the

问题 I am new in Java and trying to add evaluate method to my class. The ExpTree class and its testing program is given to me. I wrote my code as I learned in the class, but do not know why it does not work. An evaluate() method, which returns the arithmetic evaluation of the ExpTree. This should be done recursively, so you will need 2 methods to do it. In the case where it would result in division or mod by 0, it should throw a new ArithmeticException with a descriptive String. If the tree is

问题 i want to make a single test for single instance i use j48 in FilteredClassifier like this: Remove rm = new Remove(); rm.setAttributeIndices("1"); // remove 1st attribute // classifier J48 j48 = new J48(); j48.setUnpruned(true); // using an unpruned J48 // meta-classifier FilteredClassifier fc_J48 = new FilteredClassifier(); fc_J48.setFilter(rm); fc_J48.setClassifier(j48); tdta.dataSet.setClassIndex(tdta.dataSet.numAttributes() - 1); fc_J48.buildClassifier(tdta.dataSet); now, i try those
