python中的redis定义

redis官方介绍，python的redis客户端可以一处定义，处处使用。到底是不是这样呢？是不是只要在配置文件里定义一次，不管在哪都可以使用了？

下面用代码说明:

 import redis
 import threading

 redis_store = redis.Redis(host='127.0.0.1', port=6380, db=0, password='dahai123')

 def test_redis_fun(x):
     redis_store.set(x, ')

 def test_redis():
     threads = [threading.Thread(target=test_redis_fun, args=(i, )) for i in range(1, 100)]
     [t.start() for t in threads]
     [t.join() for t in threads]

 def cat_result():
     all_numbers = [redis_store.get(x) for x in range(1, 100)]
     return all_numbers

 if __name__ == '__main__':
     redis_store.flushdb()
     test_redis()
     result = cat_result()
     print result

这是一个多线程操作一个redis的connection，看结果如下:

['123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456', '123456']

结果应该没错，看来官方是正确的，redis客户端只要定义一处，就可以处处使用了，以后还可以定义在配置文件里。
