简单的python多线程并发

前些天学到的线程,做下记录,以备后用:

程序如下:

import sys,time import thread def a():        for i in range(1,5):         time.sleep(0.5)         print "nhello"         time.sleep(1)

def b():     for j in range(1,5):         time.sleep(1)         print "nthen"                time.sleep(0.5) thread.start_new_thread(a,()) thread.start_new_thread(b,())

线程1执行a(),线程2执行b(),为了看出效果,加入time.sleep()

实验验证:

但是我移植到pyqt内时,发现报错: Unhandled exception in thread started by <bound method MyForm.start2 of <__main__.MyForm object at 0x012C1348>>

google之,pyqt有自己的线程机制,好吧,继续努力。
