exit

问题 I have a python package and I would like to use its classes and methods in Matlab. I know that this can be done directly since Matlab 2014b. I mean all you have to do is add py. in the beginning of your statements. So far so good, however, I couldn't figure out how to deal with context managers through MATLAB, which are invoked using the with statement. For instance, assume that we have the following class in a module called app.py, class App(object): def __init__(self, input): self._input =

问题 I need to terminate the javascript from a function so that it doesn't execute the next block of codes and other functions called by the script, which follows the current function. I found this existing question in SO : How to terminate the script in Javascript , where the solution is given as to trigger an error / exception which will terminate the script immediately. But my case is different because, My purpose of terminating the script is to prevent an error which will come from the next

问题 I learn that exit is not a keyword in Python by, import keyword print('exit' in keyword.kwlist) # Output: False But there is no reminder of NameError: name 'exit' is not defined while using it. The output of the following snippet code makes me confused. Can anyone help me out? for i in range(5): print(i) cur=i if i<2 else exit print(cur) # Output 0 1 2 3 4 Use exit() or Ctrl-D (i.e. EOF) to exit I am unable to get related info about exit from Python documentations, except for exit([code=None]

问题 I'm looking for a way to quickly exit a C++ that has allocated a lot of structures in memory using C++ classes. The program finishes correctly, but after the final "return" in the program, all of the auto-destructors kick in. The problem is the program has allocated about 15GB of memory through lots of C++ class structures, and this auto-destruct process takes about 1 more hour itself to complete as it walks through all of the structures - even though I don't care about the results. The

问题 How to exit a program with an exit code in C#? In java it would be System.exit(int code); 回答1: Either: Declare your Main function as returning int , and return a value from it, or Call Environment.Exit(int) Returning a value from Main is a little nicer than exiting the process in the middle of a method, but this is presumably the same advice that applies to Java, C or C++. 来源： https://stackoverflow.com/questions/3529393/how-to-exit-a-program-with-an-exit-code-c-sharp

问题 Is there any difference between the two. I was reading an article ( http://www.javalobby.org/java/forums/t17933 ) about that you should always use System.exit(0); Currently I use JFrame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); The article says that even for a Java Swing Application you should add a listener WindowAdapter and and call System.exit() inside its method windowClosing(WindowEvent e) . Is there any difference? Is one method better then the other? 回答1: If you look at the

问题 when I try Building the .exe of my code in C inside NB it makes it successful, but when I try to run it inside the program I always get this error: Unable to start pty process: RUN FAILED (exit value -2, total time: 31ms) But when I go inside the Run proprieties of the project and set the "Console Type" parameter to "External Terminal" it runs in the command line OK. Any idea about what it could be? I am working with cygwin. 回答1: I fixed the problem going to Properties Project -> Run ->

问题 I am looking for a way to terminate a thread by using sys.exit(). I have two functions add1() and subtract1() , which are executed by each thread t1 and t2 respectively. I want to terminate t1 after finishing add1() and t2 after finishing subtract1() . I could see that sys.exit() do that work. Is it ok to do in such way? import time, threading,sys functionLock = threading.Lock() total = 0; def myfunction(caller,num): global total, functionLock functionLock.acquire() if caller=='add1': total+

问题 So my login Activity is the first screen you see. When you hit the back button, it exits the app, good. So I open up the app again. After logging in, I am now in my main Activity. How do I make it so when I hit the back button now, it exits the app rather than going back to the login Activity? 回答1: When you push the new activity, call finish() on the previous, otherwise it will remain on the stack, therefore appearing when you hit back and pop the current activity. Hope that helps. 回答2: try

问题 If I fail to explicitly call exit for certain function-based Bash scripts then there are additional unexpected executions for some functions. What is causing this? The behavior was first noticed while making a git alias as part of answering another user's question on StackOverflow. That alias was composed of this script ( which runs the function twice instead of once ): #!/usr/bin/env bash github(){ echo github; }; twitter(){ echo twitter; }; facebook(){ echo facebook; }; if [[ $(type -t "$1"
