问题 Just been messing around with pygame and ran into this error. CODE: import sys import pygame pygame.init() size = width, height = 600, 400 screen = pygame.display.set_mode(size) while 1: for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit(); sys.exit(); ERROR: Traceback (most recent call last): File "C:/Users/Mike Stamets/Desktop/Mygame/Pygame practice/ScreenPractice.py", line 12, in <module> pygame.quit(); sys.exit(); SystemExit I was just trying to set a while loop so

问题 I have a very basic C# console app that connects to a db, executes a query, closes the connection, and exits out of the app. The problem is, the app takes almost 3 seconds to exit. I have displayed the time at each step to see why it is running slowly and it isn't during any of the processing, just when it exits out of the app. Does anyone know how to speed this up? Here is the output: Opening Connection:94ms 26:OK Closing Connection:356ms Closed Connection:357ms Exiting:358ms [Delay of about

问题 Lets say I have the following scripts a.sh echo in a if test 1 -ne 2; then echo oops exit 1 fi b.sh echo in b ./a.sh echo in b 2 When running b.sh, I want it to exit if a.sh exited. How do I do this? (The current output is in b in a oops in b 2 And that's not what I want) Thanks, Rivka 回答1: check return status of a command, corresponding variable is $? . alternatively, you can short-circuit using command || exit 回答2: echo in b ./a.sh && echo in b 2 This basically checks that the first script

问题 I have a question to all the experienced Teamcity users out there. I would like to exit out of a job based on a particular condition, but I do not want the status of the job as a failure. Is it possible to mark a job as successful even when you exit out of the job with an "exit code 1" or any pointers to achieve the same (exit out of a Teamcity job but mark the job as successful) through an alternative way is greatly appreciated! Thanks! 回答1: You can use TeamCity service messages to update

问题 I have a python script that draws a koch snowflake. Everything works fine, except if I close the tutle graphics window before the drawing finished I get a long error with this as a final line: tkinter.tclerror: invalid command name ".38006576". I think it's like in java.swing: exit_on_close. Which is not the default. However I haven't found something like this for python turtle. Any suggestions how to avoid this? import turtle import sys import easygui as eg def isNum(s): try: int(s) return

问题 C program: pid = fork(); if (pid == 0) { execv("Golang Process"); } else (pid > 0) { wait(&status); printf("process %d status: %d\n", pid); } Golang Program: func main() { ...... os.Exit(1) } But, output is: process XXX status: 256 if set os.Exit(2), output is: process XXX status: 512 if set os.Exit(3), output is: process XXX status: 768 Why? 回答1: See wait manual: If status is not NULL, wait() and waitpid() store status information in the int to which it points. This integer can be inspected

问题 I'm currently making an effort to create test cases for one of our java applications. In my code, my java application calls a batch file, which in turn starts a separate java process, that returns an error code that I need to consume from the calling java application. I'm doing the following to invoke my batch file: Process process = runTime.exec(new String[]{"cmd.exe","/c",scriptPath}); exitValue = process.waitFor(); The batch file is as follows: @echo off cd %~dp0 java -cp frames

问题 How do you make it so the game can exit but not have the code in the main class, have it in a different class? 回答1: You can create a method: //Inside of game1.cs public void Quit() { this.Exit() } I'm assuming you want to quit the game on a menu component, in which case you will need to pass the instance of game1 to the component, perhaps add it as a parameter in the menu components update method. public void Update(GameTime gameTime, Game1 game) { if(key is pressed) { game.Quit(); } } I'm

问题 I'm executing a script in lua: os.execute("sh manager/scripts/update_system.sh" .. " " .. f) And I want to get the output of the script( if exit status is 7 returns 7). I tried local output = os.execute("sh manager/scripts/update_system.sh" .. " " .. f) print(output) but it returns some weird numbers like 512 Any idea how to resolve this? 回答1: It seems like the outputs of os.execute are all 256 multiples. Don't ask me why, it must be a bug. So I did this: local exit = os.execute("sh manager
