游戏中的事件
1、 鼠标相关的事件
鼠标事件要关注事件发生的位置:event.pos
2.键盘事件
键盘事件要关注哪个键被按了:event.key

Python中永threading模块实现多线程,
一个thread类就是一个线程类,需要几个线程就创建几个thread类

#同时创建三个下载任务
'''
Thread(target,args)
target:Function,需要传一个参数(这个函数的内容会在子线程中执行)
args :元组,target对应函数的参数
当通过创建好的子线程对象调用start方法的时候,会自动在子线程中调用target对应的函数,
并且将args中的值作为实参传给target

可以通过写一个类继承Thread类,来创建属于自己的线程类
1.声明类继承Thread
2.重写run方法
3.需要线程对象的时候,创建当前声明的子类的对象;然后通过start方法在子线程中执行run方法的任务

#若要判断子线程是否全部结束,可以将各子线程放在一个子线程中后调用join方法
