一、创建线程 在threading模块中，创建线程是一个基本的操作。我们可以使用Thread类的构造函数来创建新的线程。以下是一个简单的例子：import threadingdef my_function(): print("This is my thread!")# 创建线程my_thread = threading.Thread(target=my_function)# 启动线程my_thread.start()# 等待线程结束my...
_thread.start_new_thread(function,args[,kwargs]) Start a new thread and return its identifier. The thread executes the functionfunctionwith the argument listargs(which must be a tuple).The optionalkwargsargument specifies a dictionary of keyword arguments. When the function returns, the thread s...
threading.Thread(target=craw,args=(url,)) for thread in threads: thread.start() for thread in threads: thread.join() print("multi_thread end") if __name__=='__main__': start=time.time() single_thread() end=time.time() print("single thread cost:",end-start) start=time.time() ...
