簡單的python多線程並發

前些天學到的線程,做下記錄,以備後用:

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,())

線程1執行a(),線程2執行b(),為了看出效果,加入time.sleep()

實驗驗證:

但是我移植到pyqt內時,發現報錯: Unhandled exception in thread started by <bound method MyForm.start2 of <__main__.MyForm object at 0x012C1348>>

google之,pyqt有自己的線程機制,好吧,繼續努力。
