python thread 並發且順序運行樣本

複製代碼 代碼如下:#-*- coding:utf-8 -*-
import threading
import time
def fun(name, ls_name, front_thread = None):
'''''
線程啟動函數
通過front_thread來使用線程有序的運行
'''
time.clock()
time.sleep(2)
# 如果front_thread存在，則在front_thread運行完成後，才運行當前線程
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()
# 逐一啟動1000個線程
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)

# 等待所有線程結束
for t in ls_thread:
t.join()

print 'ls_result_name:', ls_result_name
print "main thread:%s" % time.clock()

運行結果為：
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]
