在Python中,可以使用_thread.exit()方法来退出线程。下面是退出线程的代码: import_threadimporttimedefmy_thread():# 线程的任务代码print("线程开始执行")foriinrange(5):print("线程执行中...")time.sleep(1)ifi==3:# 在第4次循环时退出线程_thread.exit()print("线程执行结束")_thread.start_new_thre...

print('Thread alive, and it won't die on program termination') t1 = threading.Thread(target=func) t1.start() time.sleep(2) sys.exit() 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 需要注意的是,当主程序通过sys.exit()退出的时候,子线程t1仍然存活。在Python中,任何non-daemon...
A thread is an execution context, which is all the information a CPU needs to execute a stream of instructions. Suppose you're reading a book, and you want to take a break right now, but you want to be able to come back and resume reading from the exact point where you stopped. One...

这一切基于假设:Python 中的标准扩展module 是不会在运行时动态改变的。实际上Python 内部提供的module 可以分成两类,一类是C 实现的builtin module 如thread,一类是用python 实现的标准库module。 p328:设置搜索路径、site-specific 的 module 搜索路径 sys.path 即 sys.__dict__['path'] 是一个 PyListObject...
