代码如下:
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", 1,))
_thread.start_new_thread(print_time, ("Thread-2", 2,))
except:
print("Error: 无法启动线程")
while 1:
pass
网上找的代码,最后的while循环让我非常困惑,这是怎么做到运行的?
