2. 使用threading模块 - 创建线程:通过`threading.Thread`类创建新线程,并指定线程要执行的函数。 - 启动线程:使用`start()`方法启动线程,该方法会调用线程的run()方法。 - 同步线程:为了确保线程安全,可以使用`threading.Lock`或其他同步机制来控制对共享资源的访问。 3. 管理线程 - 线程池:使用线程池可以减少...
用start方法来启动线程,真正实现了多线程运行,这时无需等待run方法体代码执行完毕而直接继续执行下面的代码。通过调用Thread类的start()方法来启动一个线程,这时此线程处于就绪(可运行)状态,并没有运行,一旦得到cpu时间片,就开始执行run()方法,这里方法 run()称为线程体,它包含了要执行的这个线程的内容,run方法运行...
If you're only interested in debugging a Python script, the simplest way is to select the down-arrow next to the run button on the editor and selectPython Debugger: Debug Python File. If you're looking to debug a web application using Flask, Django or FastAPI, the Python Debugger extensio...

There are a few forms of exceptions that allow for catching multiple exception types and so on, but the core form is the same. As with C#/CLR exceptions, if the exception passes outside of the top-level function in the currently executing program, the thread will terminate and pri...

你可以调用 thread.isDaemon()函数来判 断其 daemon 标志的值。新的子线程会继承其父线程的 daemon 标志。整个 Python 会在所有的非守护 线程退出后才会结束,即进程中没有非守护线程存在的时候才结束。 Thread 类 Thread类提供了以下方法: run(): 用以表示线程活动的方法。
