Question

我正在尝试学习“线程”模块。但是，我不确定我是否能够创建多个线程。

import threading
import time
def somefunction():
    for loop in range (10):
        print "thread sleeps for 20 seconds"
        time.sleep(20)
        print "thread %d woke up"

counter = 0
while counter < 10:
     threader = threading.Thread(target=somefunction())
     counter = counter +1

当我运行以下命令时，它只返回一个NLWP。

ps axo pid,ppid,rss,vsz,nlwp,cmd | grep -i python

我做错了什么？

您必须使用参数target中的引用到somefunction，而不是调用该函数。

import threading
import time
def somefunction():
    for loop in range (10):
        print "thread sleeps for 20 seconds"
        time.sleep(20)
        print "thread %d woke up"

for counter in range(10):
     threader = threading.Thread(target=somefunction)

线程模块。不确定我是否创建了多个线程
