thread = CustomThread(daemon = True, extra_info='This is extra info from the thread.') # start the thread thread.start() # wait for the thread to finish print('Waiting for the thread to finish') thread.join() 设置线程 在新建线程过程中,可以一并设置以下两个线程属性:是否守护线程和线程名...
下面是一个简单的线程示例: importthreadingimporttimedefworker():print("Worker thread is starting.")time.sleep(2)# Simulating a long taskprint("Worker thread is done.")# Create a threadt=threading.Thread(target=worker)t.start()# Wait for the thread to finisht.join()print("Main thread is ...
set() # 设置事件,表示任务完成 def main(): event = threading.Event() thread = threading.Thread(target=worker, args=(event,)) thread.start() print("Main thread waiting for worker thread to finish") event.wait() # 等待事件被设置 print("Main thread continues") if __name__ == "__main...
使用Python的pdb库进行调试:pdb是Python的内置调试器,可以帮助你设置断点、单步执行代码、查看变量值等。你可以在wait()函数之前设置一个断点,然后使用pdb进行调试。 import threading import pdb import time def worker(): print("Worker thread started") time.sleep(2) print("Worker thread finished") main_thr...

programming_thread.start() progress_bar_thread.start() # Wait for both threads to finish programming_thread.join() progress_bar_thread.join() print('finished') 但由于我需要从不同的模块调用这一部分,我尝试这样实现它: main: import further_threading_test ...
