loop.run_forever(): 在调用 stop() 之前将一直运行。
Very simple and handy. eg: timer=wx.Timer(parent,-1)# Then you use thetimer.Stop()#ortimer.Start()## In your events method. check it out ;) Share FacebookTwitterLinkedIn Reply to this topic Be a part of the DaniWeb community ...

whileTrue: print(next(iterator)) exceptStopIteration: pass This example creates an iterator that loops through a list of numbers using the built-in iter() method. Furthermore, when we loop through the iterator in a while loop to try to print the next item, we use the built-in next() ...

= EPOLL_CTL_DEL为true,则需要调用copy_from_user函数将用户空间传过来的event事件拷贝到内核的epds变量中。因为,只有删除操作,内核不需要使用进程传入的event事件。 接着连续调用两次fdget分别获取epoll文件和被监听文件(以下称为目标文件)的file结构变量(备注:该函数返回fd结构变量,fd结构包含file结构)。 接下来就...
CPython versions tested on: 3.12, 3.13 Operating systems tested on: Windows The problem appears to be related to how the event loop is being stopped from outside the thread where it's running. To understand this better, let's look at the relevant parts of the asyncio documentation: ...
