### Java客户端：Jedis ###

#### Jedis基本使用 ####

##### string #####

jedis.set("hello", "world");
    //[Out]: OK
    jedis.get("hello");
    //[Out]: world
    jedis.incr("counter");
    //[Out]: 1

##### hash #####

jedis.hset("myhash", "f1", "v1");
    jedis.hset("myhash", "f2", "v2");
    jedis.hgetAll("myhash");
    //[Out]: {f1=v1,f2=v2}

##### list #####

jedis.rpush("mylist", "1");
    jedis.rpush("mylist", "2");
    jedis.rpush("mylist", "3");
    jedis.lrange("mylist", 0, -1);
    //[Out]: [1,2,3]

##### set #####

jedis.sadd("myset", "a");
    jedis.sadd("myset", "b");
    jedis.sadd("myset", "a");
    jedis.smember("myset");
    //[Out]: [b,a]

##### zset #####

jedis.zadd("myzset", 99, "tom");
    jedis.zadd("myzset", 66, "paper");
    jedis.zadd("myzset", 33, "james");
    jedis.zrangeWithScore("myzset", 0, -1);
    //[Out]: [[["james"], 33.0],[["paper"], 66.0],[["tom"], 99.0]]

### Python客户端：redis-py ###

#### 安装redis-py ####

sudo pip install redis
    
    easy_install redis

#### 简单使用 ####

import redis
    
    client = redis.StrictRedis(host = "127.0.0.1", port = 6379)
    key = "hello"
    setResult = client.set(key, "python-redis")
    print setResult
    value = client.get(key)
    print "key: " + key + ", value: " + value

##### string #####

client.set("hello", "world")
    # True
    client.get("hello")
    # world
    client.incr("counter")
    # 1

##### hash #####

client.hset("myhash", "f1", "v1")
    client.hset("myhash", "f2", "v2")
    client.hgetall("myhash")
    # {"f1":"v1", "f2":"v2"}

##### list #####

client.rpush("mylist", "1")
    client.rpush("mylist", "2")
    client.rpush("mylist", "3")
    client.lrange("mylist", 0, -1)
    # ["1","2","3"]

##### set #####

client.sadd("myset", "a")
    client.sadd("myset", "b")
    client.sadd("myset", "a")
    client.smenber("myset")
    # set(["a","b"])

##### zset #####

client.zadd("myzset", "99", "tom")
    client.zadd("myzset", "66", "pater")
    client.zadd("myzset", "33", "james")
    client.zrange("myzset", 0, -1, withscores=True)
    # [("james",33.0),("pater",66.0),("tom",99.0)]
