That would explain why the stack trace appears more than once. The child is trying to wait on its own non-existent child.也可能一次处理多个相同类型的排队信号，所以我不建议在信号处理程序中使用wait().Also more than one queued signal of the same type may be handled at once, so I don't recommend using wait() in the signal handler. 这篇关于Python多处理问题/误解的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
