redis与python交互

<h1 id="strictredis对象⽅法">StrictRedis对象⽅法

• 通过init创建对象，指定参数host、port与指定的服务器和端⼝连接，host默认为localhost，port默认为6379，db默认为0
  sr = StrictRedis(host=,port=6379,db=简写
  sr=StrictRedis()

• 根据不同的类型，拥有不同的实例⽅法可以调⽤，与前⾯学的redis命令对应，⽅法需要的参数与命令的参数⼀致

• set
• setex
• mset
• append
• get
• mget
• key

• exists
• type
• delete
• expire
• getrange
• ttl

• hset
• hmset
• hkeys
• hget
• hmget
• hvals
• hdel

• lpush
• rpush
• linsert
• lrange
• lset
• lrem

• sadd
• smembers
• srem

• zadd
• zrange
• zrangebyscore
• zscore
• zrem
• zremrangebyscore

• 在桌面上创建redis目录
• 使用pycharm打开 redis目录
• 创建redis_string.py文件
