一、线程创建方法
1. 普通创建

import threadingdef run(name): for i in range(3): print(name)if __name__ == '__main__': t1 = threading.Thread(target=run, args=("t1",)) t2 = threading.Thread(target=run, args=("t2",)) t1.start() t2.start()--------------------------------------------t1t2t2t1t2t1 |
2. 自定义线程类

import threadingclass MyThread(threading.Thread): def __init__(self, name): super(MyThread, self).__init__() self.name = name def run(self): for i in range(3): print(self.name)if __name__ == "__main__": t1 = MyThread("t1") t2 = MyThread("t2") t1.start() t2.start() |
二、线程的使用
1.守护线程
子线程会随着主线程的结束而结束
t = threading.Thread(target=run, args=("t1",))
t.setDaemon(True) # 把子进程设置为守护线程，必须在start()之前设置
t.start()
2.主线程等待子线程结束
t = threading.Thread(target=run, args=("t1",))
t.setDaemon(True)
t.join() # 设置主线程等待子线程结束
t.start()
3.互斥锁
