python学习－线程、进程简洁使用

python的线程池和进程池很pythonic

进程

<pre>from multiprocessing import Pool
def hello(name):
print('hello ' + name)
if __name__ == '__main__':
names=['hao','haohao','haort']
pool = Pool(processes=3)
pool.map(hello,names)
pool.close()
pool.join()
</pre>

线程

<pre>from multiprocessing.dummy import Pool
def hello(name):
print('hello ' + name)

if __name__ == '__main__':
names=['hao','haohao','haort']
pool = Pool(processes=3)
pool.map(hello,names)
pool.close()
pool.join()
</pre>

线程池和进程池导入包不一样，其他实现一样。只需要初始化池的大小，构造处理函数，以及处理列表，利用map方法即可，是不是很pythonic。
