Python 创建线程的方法

• 使用的是 threading 模块

• 代码如下：

      1 #!/usr/bin/python3
      2
      3 import threading
      4 import time
      5
      6 exitFlag = 0
      7        // 创建线程的类
      8 class myThead (threading.Thread):
      9     def __init__(self, threadID, name, counter):
     10         threading.Thread.__init__(self)
     11         self.threadID = threadID
     12         self.name = name
     13         self.counter = counter
     14     def run(self):
     15         threadLock.acquire();    // 线程同步
     16         print("start function : "+ self.name)
     17         print_time(self.name, self.counter, 5)
     18         print("exit function :" + self.name)
     19         threadLock.release()    // 线程同步释放
     20
     21       // 线程调用的函数
     22 def print_time(threadName, delay, counter):
     23     while counter:
     24         if exitFlag:
     25             threadName.exit()
     26         time.sleep(delay)
     27         print ("%s : %s" % (threadName, time.ctime(time.time())))
     28         counter -= 1
     29
     30 threadLock = threading.Lock()
     31 threads = []
     32
     33 thread1 = myThead(1, "Thread-1", 1);    // 创建线程的实体
     34 thread2 = myThead(2, "Thread-2", 2);
     35 thread3 = myThead(3, "Thread-3", 3);
     36
     37 thread1.start()
     38 thread2.start()
     39 thread3.start()
     40
     41 threads.append(thread1);    // 加入线程数组
     42 threads.append(thread2);
     43 threads.append(thread3);
     44
     45 for t in threads:
     46     t.join();    // 线程执行
     47
     48 print("exit main process");
