file_path = 'example.txt' thread = threading.Thread(target=delete_file, args=(file_path,)) thread.start() thread.join() 4、确保线程安全 为了确保线程安全,需在删除文件函数中加锁,防止多个线程同时访问同一文件导致资源竞争。 lock = threading.Lock() def delete_file(file_path): with lock: try:...
# The main thread isn't finished yet, so its thread state lock can't have # been released. assert tlock is not None assert tlock.locked() tlock.release() _main_thread._stop() t = _pickSomeNonDaemonThread() while t: t.join() t = _pickSomeNonDaemonThread() _main_thread._delet...
在上述代码中,我们使用threading.Thread()函数来创建多个线程,并将它们存储在一个列表中。每个线程都会调用delete_files函数来删除文件。 步骤3: 定义文件删除函数 接下来,我们需要定义文件删除函数。以下是删除文件的代码: importos# 删除文件defdelete_files(file_list):forfileinfile_list:try:os.remove(file)excep...
lock=threading.Lock()#创建线程thread_add = threading.Thread(target=account.add, args=(lock,), name='Add') thread_delete= threading.Thread(target=account.delete, args=(lock,), name='Delete')#启动线程thread_add.start() thread_delete.start()#等待线程结束thread_add.join() thread_delete.join(...
Thread): def run(self): for i in range(2): # 等待1秒后执行 time.sleep(3) # name属性中保存的是当前线程的名字 msg = "我是线程 "+self.name+' @ '+str(i) print(msg) def test(): for i in range(3): t = MyThread() t.start() if __name__ == '__main__': test() 我...
我们通过把interpreters.create函数传递给Thread,它会自动在线程内部生成新的子解释器。我们也可以结合这两种方法，并将辅助函数传递给threading.Thread：import timedefrun_in_thread(): interp = interpreters.create(isolated=True) t = threading.Thread(target=_run_output, args=(interp, dedent(""" imp...
thread.interrupt_main():在主线程中引发一个KeyboardInterrupt(一般是Ctrl+C或者是delete)异常。子线程能够通过这个函数中断主线程。 thread.exit(): 触发SystemExit异常。假设没有被捕获(不作出处理)。将会影响此线程退出终止。 thread.allocate_lock():
Python首先会通过PyThreadState_Clear清理当前线程所对应的线程状态对象。所谓清理,实际上比较简单,就是对线程状态对象中维护的东西进行引用计数的维护。随后,Python释放GIL,释放GIL的操作是在PyThreadState_DeleteCurrent中完成的。 在PyThreadState_DeleteCurrent中,首先会删除当前的线程状态对象,然后通过PyEval_ReleaseLock...
