首先，我研究了所有其他解决方案。我确保我的IDE /编辑器（Atom）不会捕获输入。我一直在查看是否我的任何代码都笨拙地阻止了Ctrl-C。我用了time.sleep，signal，threads，就给它命名。我无法弄清楚为什么发送Ctrl-C不会停止我的Python程序（但是通过Activity Monitor杀死它）。这是代码

user_data_manager只是我用于连接JSON文件的一段代码，而get_data.py看起来像这样

我不明白为什么get_data或main中的某些内容会干扰捕获SIGINT的行为，但是我不是专家。为什么我不能退出代码？
编辑：如果有帮助，我可以在main（）打印之前完全退出，但是在退出之前不能退出。
答案 0 :(得分：0)
我尝试用IDLE中的KeyboardInterrput测试，它完美地引发了KeyboardInterrupt。如果确实不适合您，建议您使用其他方法来管理热键。
编辑：KeyboardInterrpu出现时出现，但用except语句无法检测到。 可能的最可能的原因是KeyboardInterrupt没有继承自BaseException，后者具有允许捕获错误的编码。希望这可以帮助！
