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. 自定義線程類

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、線程的使用
1.守護線程
子線程會隨著主線程的結束而結束
t = threading.Thread(target=run, args=("t1",))
t.setDaemon(True) # 把子進程設置為守護線程，必須在start()之前設置
t.start()
2.主線程等待子線程結束
t = threading.Thread(target=run, args=("t1",))
t.setDaemon(True)
t.join() # 設置主線程等待子線程結束
t.start()
3.互斥鎖
