python3 多线程 用函数方法实现

import _thread

import time

# 为线程定义一个函数

def print_time( threadName, delay):

count = 0

while count < 5:

time.sleep(delay)

count += 1

print ("%s: %s" % ( threadName, time.ctime(time.time()) ))

# 创建两个线程

try:

_thread.start_new_thread( print_time, ("Thread-1", 2, ) )

_thread.start_new_thread( print_time, ("Thread-2", 4, ) )

except:

print ("Error: 无法启动线程")

while 1:

pass
