python多线程 简单例子

多线程, 简单的理解就是让我们可以同时做多件事情, 以下为简单例子.

import threading
def first():
  print("do one thing")

def second():   
  print("do another thing")

threads = []

t1 = threading.Thread(target = first)
threads.append(t1)

t2 = threading.Thread(target = second)
threads.append(t2)

if __name__ == '__main__':
    for t in threads:
        t.start()
