#使用threading模块创建线程
import threading,time
def process():
    for i in range(3):
        time.sleep(1)
        print('thread name is %s'%threading.current_thread().name)
if __name__=='__main__':
    print('主线程开始')
    threads=[threading.Thread(target=process) for i in range(4)]# 创建4个线程存入列表
    for t in threads:
        t.start()
    for t in threads:
        t.join()
    print('主线程结束')
运行结果：
主线程开始
thread name is Thread-4
thread name is Thread-2
thread name is Thread-1
thread name is Thread-3
thread name is Thread-1
thread name is Thread-4
thread name is Thread-3
thread name is Thread-2
thread name is Thread-3
thread name is Thread-1
thread name is Thread-4
thread name is Thread-2
主线程结束
