Python全局异常处理 [英] Python Global Exception Handling

问题描述

所以我想在全球范围内捕获 KeyboardInterrupt ，并且很好地处理它。我不想将我的整个脚本包含在一个巨大的try / except语句中，因为这听起来很大。有没有办法这样做？

So I want to catch KeyboardInterrupt globally, and deal with it nicely. I don't want to encase my entire script in a huge try/except statement, because that just sounds gross. Is there any way to do this?

推荐答案

如果这是在命令行执行的脚本，可以封装你的运行在 main（）中的时间逻辑，如果__name__ =='__main __'并将其包装起来，调用它 / p>



If this is a script for execution on the command line, you can encapsulate your run-time logic in main(), call it in an if __name__ == '__main__' and wrap that.

if __name__ == '__main__':
    try:
        main()
    except KeyboardInterrupt:
        print 'Killed by user'
        sys.exit(0)
