python多執行緒例項

a、建立乙個thread的例項，傳給他乙個函式

import threading

from time import sleep
def thread_body(arg1,arg2):
print "i am a child thread",arg1,arg2
sleep(10)
print "end child thread"
def main():
print "____main_____start:"
thread_target=threading.thread(target=thread_body,args=("hello","test"))
print "child start"
thread_target.start()
print "i am main thread"
thread_target.join()
print "end_main"
if __name__=='__main__':
main()

b、建立乙個thread的例項、傳給他乙個可以呼叫的類物件

import threading

from time import sleep
def thread_body(arg1,arg2):
print "i am a child thread",arg1,arg2
sleep(10)
print "end child thread"
class thread_class(object):
def __init__(self,func,args,name=''):
self.func=func
self.name=name
self.args=args
def __call__(self):
def main():
print "____main_____start:"
# thread_target=threading.thread(target=thread_body,args=("hello","test"))
thread_target=threading.thread(target=thread_class(thread_body,("hello",'world'),"child_test"))
print "child start"
thread_target.start()
print "i am main thread"
thread_target.join()
print "end_main"
if __name__=='__main__':
main()

c、從thread派生出乙個子類、建立乙個子類的例項。

import threading

from time import sleep
def thread_body(arg1,arg2):
print "i am a child thread",arg1,arg2
sleep(2)
print "end child thread"
class thread_child(threading.thread):
def __init__(self,func,args,name=''):
threading.thread.__init__(self)
self.name=name
self.args=args
self.func=func
def getresult(self):
return self.res
def run(self):
print 'child run'
def main():
print "____main_____start:"
thread_target=thread_child(thread_body,("hello","world"),"test")
print "child start"
thread_target.start()
print "i am main thread"
thread_target.join()
print "end_main"
