for-loop

问题 I'd like to run two dependent non-nested for loops. In essence they are two simultaneous Markov chains, where one loop needs to check a value in the other loop. Is it there a right way to do this? Is there a wrong/inefficient way to avoid? Imaginary example: Imagine two people are walking round a room and touching things: I record those things they touch in two separate arrays. Those are my two Chains or for loops. That's fine as long as their behaviour is independent. But I'd like to change

问题 I am trying to using following code to extract entities from text available in DataFrame. for i in df['Text'].to_list(): doc = nlp(i) for entity in doc.ents: if entity.label_ == 'GPE': I need to store text of first GPE with it's corresponding column of text. Like for instance if following is text at index 0 in column df['Text'] Match between USA and Canada was postponed then I need only first location(USA) in another column such as df['Place'] at the corresponding index to Text which is 0. df

问题 I get an infinite loop because of this small bit of code. It becomes fixed if I declared the var i to any value (i.e. var i = 0) before the loop, and I'm not sure why. Could someone who's familiar with javascript's intricacies explain to me what's going on here? for (num = 1; num <= 2; num++) { for (i = 1; i < num; i++) { console.log("hi"); } } 回答1: Since i was not declared as a local var , your code is, in-effect altering variables/objects window.i as well as window.num Adding var keywords

问题 I was not really clear with the post increment operator that I always used with for loops. My latest and newly acquired understanding of post increment operator is the following: int a = 5 int b = a++ //a will increment and return back its old value 5 so b = 5 Armed with this new knowledge i decided to understand/apply it to the places where i commonly used the post increment operator as in a for loop . Now it seems like I am lost since I am ending up with the wrong output theoretically

问题 I am a newbie and I am to fulfill an exercise which is to write a simple program which would produce an array in console: 0, 0, 1, 0, 1, 2, I failed at google searching similar problems which would direct me at a solution. I will greatly appreciate your help. This is what i have been trying to build upon, but I am completely stuck: public static void main(String[] args) { // TODO Auto-generated method stub int[] table = new int[11]; for ( int i = 0; i <=10; i++){ table[i] = i; System.out

问题 I am using a genetic interpretation software called SAIGE-GENE. The algorithm looks like this (full algorithm at https://github.com/weizhouUMICH/SAIGE/wiki/Genetic-association-tests-using-SAIGE#step-2--performing-the-region--or-gene-based-association-tests): It involves multiple different files being entered with chromosome numbers in their file names (1 to 22). SPAGMMATtest = function( vcfFile = "", vcfFileIndex = "", vcfField = "DS", groupFile ="", savFile = "", savFileIndex = "",

问题 This code I'm using is from this previously asked question. This question has been asked and answered plenty of times but I'm specifically asking for the order to be listed by size from largest to smallest. public static void main(String[] args) { String inputedWord = "ABIGWORD"; for (String str : breakStringIntoPieces(inputedWord, 2)) { System.out.print("\n") + str; } } //Pass in word and minimum //substring length to print public static List<String> breakStringIntoAllPossibleSubstrings

问题 I'm new to Dart and therefore having trouble with asynchronous programming. I'm trying to loop through a list of elements (let's call them ingredients for now) and query the database for recipes which contain the ingredient. To achieve this, I have a list 'ingredientsSelectedList' and pass it over to a future which is supposed to query the Firestore Database and add the result to the 'possibleRecipes' List. The problem is, that I can't figure out how to 'await' the for loop to finish, before
