新建一个Thread类,重写run()方法: publicclassMyThread extends Thread { @Overridepublicvoidrun() { System.out.println("子线程执行完毕"); } } 新建测试类,测试Join()方法: publicclassTestThread {publicstaticvoidmain(String[] args) {//循环五次for(inti =0; i <5; i++) { MyThread thread=new...
线程多任务实现2:定义类继承threading.Thread,然后重写run方法(run方法相当于功能函数) 代码语言:javascript 代码运行次数:0 运行 AI代码解释 from threading import Thread import threading import os import random import time class the_cosmetic(threading.Thread): def __init__(self, num): self.num = num ...
thread1.start()# 启动线程1 thread2.start()# 启动线程2 thread1.join()# 等待线程1结束 thread2.join()# 等待线程2结束 print("Main thread finished. If threads deadlocked, this might not be reached or take very long.") 代码解释:Thread-AThenB先获取lock_a再尝试获取lock_b,而Thread-BThenA先...
class MyThread(threading.Thread): def start(self): print('start---') super().start() # 调用父类的start()和run()方法 def run(self): print('run---') super().run() # 调用父类的start()和run()方法 t = MyThread(target=add, name="MyThread", args=(1, 2)) t....
with语句利用现有的上下文管理器,创建一个运行时上下文(Runtime Context),在上下文管理器的控制下运行一组语句。相比于传统的try…finally结构,with语句能够使代码更清晰、更安全、可重用,而且Python标准库中的许多类都支持with语句。 (1)with语句的语法如下: with expression as target_var: do_something(target_var...
def run(self): #重写run方法 for y in range(100): print('运行中'+str(y)) x=Xc() x.start() #开始线程 x.join() #等待子线程结束 也可以这么写: Xc().run() 和上面的效果是一样的 2、多线程 class Xc(t.Thread): #继承Thread类 ...
the curent threading MainThread is running the curent threading Thread-1 is running the curent threading MainThread is ended the curent threading Thread-1 is ended 但如果为线程实例添加t.setDaemon(True)之后,如果不加join语句,那么当主线程结束之后,会杀死子线程。代码: ...
