python:redis简单操作

一,安装redis-py

• pip install redis
• easy_install redis

二，简单用法

import redis

# 连接redis服务器
def conn_redis():
    r = redis.StrictRedis(host='10.21.25.196', port=6379, db=0)
    return r

#hash
def test_hash():
    r = conn_redis()  # 连接redis数据库
    result = r.hgetall('1861098')  # 获取该字典中所有k-V对
    print result.keys()  # 获取所有key
    print result.values()  # 获取所有value
    for key, value in  result.items():  # 遍历key，value对
        print key, '------>', value
    print result.items()  # 输出所有key，value对（以元组的方式）
    print result.has_key('count')  # 判断时候存在某个键值
    return result

def test_set():
    r = conn_redis()  # 连接redis数据库
    result = r.smembers('test')  # 获取该集合中所有元素
#     print len(result)#求集合长度
#     print list(result)#将set转化成list
#     for key in result:
#         print key

    return list(result)

def test_simple():
    r = conn_redis()
#     r.set('foo','bar')
    print r.get('foo')

def test_pipe():
    r = conn_redis()
    pipe = r.pipeline(transaction=False)
    result = pipe.set('foo', 'lky').get('foo').execute()
    print result

def test_transaction():
    r = conn_redis()
    pipe = r.pipeline()
    pipe.set('foo', 'bar')
    pipe.get('foo')
    result = pipe.execute()
    print result
