QUESTION
I'm reading domains from a file and check whether the domain format is correct or not. if domain is correct write it to true.txt and if not, write it to wrong.txt. My problem is that the program after reading some domains from file throws an exception. I've attached my code and errors below:

QUESTION
Given the following code:
...ANSWER
Answered 2020-Jan-21 at 20:05There are two reasons why you are observing this.
The first is because of the parameters you passed to your Tfidf Vectorizer. You should be doing
TfidfVectorizer(use_idf=True, ...), because it is the idf part of the tfidf (remember that tf-idf is the product of term frequency and inverse document frequency) that will penalize words that appear in all documents. By settingTfidfVectorizer(use_idf=False, ..), you are just considering the term frequency part, which obviously leads to stopwords having a larger scoreThe second is because of your data. Suppose you fixed the code problem above, your corpus is still very very small, just two documents. This means that any word that appears in both books will get penalized the same way. "courage" might appear in both books, just as "the", and so given they both appear in each document of your corpus, their idf value will be the same, causing stopwords to again have a larger score because of their larger term-frequency
QUESTION
I'm currently learning JS/jQuery and thought I'd code a quiz for practice. While I managed to code the basics of the quiz I am struggling with a crucial part of my code.
In this quiz, I have an Array containing 10 objects. Each object has a question (String), options (Array), an answer (String) and a Boolean which indicates whether or not a question has been answered. Further, I filter this array to include only those elements, that haven't been asked/answered yet. However, this unansweredArr always contains 10 elements, even if I call the function again before asking the new question.
What I aim to do is the following:
- Generate an array, that holds every question that hasn't been answered yet. This is being done with
var unansweredArr = data.filter(function(question){
return question.answered === false;
});
- Then I generate a random number, which will be used to grab an element out of this array. Said element then is being displayed in my HTML
- When the player clicks on an option, the given answer will be checked. If correct, the player's score will be increased by 1 and the next question will be asked. Also
answered: falsewill be set toanswered: trueon that specific question.
Until step 3, everything works like a charm (for me ;)) However, step 4 and further are my main problems.
- Basically, step 2 and 3 should be repeated. Thus, the array should filter for every Object with
answered: false. This array should update and contain 9 elements now - However, it doesn't. It still contains 10 elements and I don't know why. I tried to call the filter function again, without success. I tried refactoring some code by moving bits and pieces around, but nothing worked for me. Additionally, when checking for the right answer, it seems like the answer to the question that has been first answered is saved and will be used to for all the other questions.
Please find my code here:
...ANSWER
Answered 2018-Feb-13 at 20:18The problem is that you define the same variables randomIndex and unansweredArr as global variables and as local variables in the function next.
When you update their value in the function next, the global variables with the same names do not change.
As a consequence you are always marking the first random question as answered:
