Python创建线程的两种方式

import threading, random, time


# 第一种创建方式 传入run方法
def thread_run(urls):
    print('Current %s is running...' % threading.current_thread().name)
    for url in urls:
        print('%s ---->> %s' % (threading.current_thread().name, url))
        time.sleep(random.random())
        print('%s ended.' % threading.current_thread().name)


print('%s is running' % threading.current_thread().name)
t1 = threading.Thread(target=thread_run, args=(['url1', 'url2', 'url3'],))
t2 = threading.Thread(target=thread_run, args=(['url4', 'url5', 'url6'],))
t1.start()
t2.start()
t1.join()
t2.join()
print('%s ended.' % threading.current_thread().name)

import threading, random, time


# 第二种继承方式
class myThread(threading.Thread):

    def __init__(self,name,urls):
        threading.Thread.__init__(self,name=name)
        self.urls = urls

    def run(self):
        print('Current %s is running...' % threading.current_thread().name)
        for url in self.urls:
            print('%s ---->>> %s' % (threading.current_thread().name, url))
            time.sleep(random.random()*3)
        print('%s ended.' % threading.current_thread().name)



print('%s is running...' % threading.current_thread().name)
t1 = myThread(name='Thread_1', urls=['url1', 'url2', 'url3'])
t2 = myThread(name='Thread_2', urls=['url4', 'url5', 'url6'])
t1.start()
t2.start()
t1.join()
t2.join()
print('%s ended.' % threading.current_thread().name)
