【Python】多线程2

threading模块

import time
import random
import threading
class Inclass:
    def __init__(self):
        print 'Inclass 初始化'
    def execIn(self,i):
        rand = int(random.random() * 10)
        print i,'---%s--开始执行，暂停%d秒' % (time.ctime(),rand)
        time.sleep(rand)
 
class Outclass:
    def __init__(self):
        print 'OutClass初始化'
    def execOut(self):
        InC = Inclass()
        length = 1000
        nloops = range(length)
        threads = []
        for i in range(length):
            t = threading.Thread(target = InC.execIn, args = (i,))
            threads.append(t)
        for i in nloops:

        for i in nloops:

        print i,'---%s--开始执行，暂停%d秒' % (time.ctime(),rand)
        time.sleep(rand)
        return i

    def run(self):
        self.res = self.func(*self.args)

        k = 0
