python thread 并发且顺序运行示例

#-*- coding:utf-8 -*- 
import threading 
import time 
def fun(name, ls_name, front_thread = None): 
''''' 
线程启动函数 
通过front_thread来使用线程有序的运行 
''' 
time.clock() 
time.sleep(2) 
# 如果front_thread存在，则在front_thread运行完成后，才运行当前线程 
if front_thread != None: 
front_thread.join() 
ls_name.append(name) 
print "thread %s : %s"% (name, time.clock()) if __name__ == '__main__': 
ls_result_name = [] 
ls_thread = [] 
time.clock() 
# 逐一启动1000个线程 
for i in range(0,10): 
if len(ls_thread) == 0: 
t = threading.Thread(target=fun, args=(i,ls_result_name,None)) 
else: 
t = threading.Thread(target=fun, args=(i,ls_result_name,ls_thread[-1])) 
t.start() 
ls_thread.append(t) 
# 等待所有线程结束 
for t in ls_thread: 
t.join() 
print 'ls_result_name:', ls_result_name 
print "main thread:%s" % time.clock()

运行结果为：
thread 0 : 1.99962006344
thread 1 : 2.00000866032
thread 2 : 2.00059113658
thread 3 : 2.00080345407
thread 4 : 2.00100068584
thread 5 : 2.00119456523
thread 6 : 2.00138593033
thread 7 : 2.00166753037
thread 8 : 2.00211758757
thread 9 : 2.0024776892
ls_result_name: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
main thread:2.003211302
