2.redis模块简单使用：

# /usr/bin/env python3
import redis

class Myredis(object):
    def __init__(self, host, port=6379):
        try:
            self.conn = redis.StrictRedis(host=host, port=port)
        except Exception as e:
            print(e)
        else:
            print('连接成功')

    def add(self, key, value):
        result = self.conn.set(key, value)
        print(result)

    def get(self, key):
        result = self.conn.get(key)
        print(result)

    def mod(self, key, value):
        result = self.conn.get(key)
        if result:
            result2 = self.conn.set(key, value)
            print(result2)
        else:
            print("key " + key + "is not found")

    def rem(self,key):
        result = self.conn.delete(key)
        if result != 0:
            print('删除成功')

if __name__ == "__main__":
    myredis = Myredis('192.168.26.131')
    myredis.add('name','wanghui')
    myredis.mod('name','baby')
    myredis.get('name')
    myredis.rem('name')
