readability

问题 I am wondering if there is a way to do the following in a more compact style: if (text == "Text1" or text=="Text2" or text=="Text3" or text=="Text4"): do_something() The problem is i have more than just 4 comparisons in the if statement and it's starting to look rather long, ambiguous, and ugly. Any ideas? 回答1: How about this: if text in ( 'Text1', 'Text2', 'Text3', 'Text4' ): do_something() I've always found that simple and elegant. 回答2: The "if text in" answer is good, but you might also

问题 Jupyter (iPython) notebook is deservedly known as a good tool for prototyping the code and doing all kinds of machine learning stuff interactively. But when I use it, I inevitably run into the following: the notebook quickly becomes too complex and messy to be maintained and improved further as notebook, and I have to make python scripts out of it; when it comes to production code (e.g. one that needs to be re-run every day), the notebook again is not the best format. Suppose I've developed a

问题 In JavaScript, the standard rules for code formatting don't seem to cut it. You still end up with messes of });}); all over the place and I don't believe I even know of established rules for the correct indention of anonymous functions declared as arguments to other functions. In short, I have trouble reading my own JavaScript, and I bet I'm not alone. I think the idea that I am coming around to is to just not define functions within other functions. Write every function with a name and as a

问题 I'm trying to insert edge labels outside the actual edge in my qgraph for readability purposes. I particularly don't like the option of include a white bg below the label, it screws up the edge. According to the manual, it is possible to adjust edge label position only along the line, but not on the side. Did anyone struggle with this before? Is it possible to circumvent this issue? Cheers 回答1: There does not seem to be a parameter for adjusting the across axis location of the edge label. One

问题 Let's say I wanted to print 5 lines. Which is the best method (for performance and readability). System.out.println(); System.out.println(); System.out.println(); System.out.println(); System.out.println(); or System.out.println("\n\n\n\n"); Is it a matter of preference or is one better than the other. It seems like it would save a lot of time using the second method. 回答1: There is a functional difference between the two. The first version outputs line breaks using the platform's preferred

问题 This question already has answers here : Multiple string comparison with C# (7 answers) Closed last year . I have this piece of code: if (filter != RECENT && filter != TODAY && filter != WEEK && filter != MONTH && filter != ALLTIME) { filter = RECENT; } Note that filter is a string and it's compared against const string types. Is there any way to do this inline and have it be more readable? Doing it with the ternary operator doesn't make it much better since I still have to repeat filter !=

问题 I am building a HTTP server for my android device. I am using a lot of IF-ELSE statements to handle differnt requests. As I will be sharing my code with other people for later use, I will have to make it as legible as possible. Right now, I can't even read my code with ease. I think the problem comes from using a lot of IF-ELSE statements in one class. For example. if(purpose.equals("readProfile"){ ..... } else if(purpose.equals("writeProfile"){ ..... } .... I tried classifying them in
