请问关于异常处理的问题
RT，这是关于小甲鱼教程的，跟着小甲鱼写这样的异常处理部分，可是我直接双击打开还是直接闪过一个cmd然后就没有了，没能够打开，只能IDLE打开之后再运行才可以，请问是为什么呢？if __name__ == '__main__':
try:
main()
except SystemExit:
pass
except:
traceback.print_exc()
pygame.quit()
input()
这是关于异常处理部分的代码 如果是在程序里raise SystemExit退出，如同测试代码一样，那么except捕获到SystemExit后运行pass就退出程序了，双击运行最后就是直接退出命令窗口，如果还想停留的话，象下面一样加一句input():
import traceback
def main():
raise SystemExit
if __name__ == '__main__':
try:
main()
except SystemExit:
pass
input() #加一句
except:
traceback.print_exc()
# pygame.quit()
input() 把代码发过来 txxcat 发表于 2020-5-4 00:39

我的意思是双击之后都没办法运行，直接就删过一个命令行窗口然后就没有了 lixiangyv 发表于 2020-5-4 13:54

这是完整的代码
我测试了主文件可以跑起来，无论在idel里还是双击运行，如果main碰到错误，会运行最后的input()，不会一闪而过，所以问题出现在前半部分代码里初始化的过程中，你在命令窗口里运行python 程序名 来启动，看看能看到什么错误提示。 请问你写了 supply、myplane、enemy、bullet 模块了吗 txxcat 发表于 2020-5-4 18:19

不用啊，你原来在那个目录下就在哪个目录下双击运行，保证资源文件和文件夹都在那个目录下就行了。cmd只是打开个命令窗口，里面的目录是可以随意转换的。我教你的方法就是转到你的程序所在目录，然后用‘python 程序名.py’ 来启动程序，这样如果有报错就可以看到，不像双击运行出错会直接关闭窗口，有了错误提示就好找出问题所在了。 txxcat 发表于 2020-5-7 22:01
