redis type of data stored on the disk inside, so the store faster, or other types of data stored in a database so more slowly
Redis database link:
When r = redis.Redis (host = "%%%%%%%", password = "HK139bc & *", db = 10, decode_responses = True) # port = 6379 default can not write db not write, the default is 0 decode_responses = True: If you do not need to be binary decode time
A string type
1, is written to the redis
r.set("key","value")
2, the data acquired in redis
r.get("key")
3, delete data
r.delete("key")
4, increase the time to failure
r.set ( "key", "yj", 10) # ( "key", "yj") key, values statement to add data pattern # 10 represents the expiration date, if it is -1, which means permanent expiring (but after restart expire)
If the increased key, increase the time to failure
r.expire("key",10)
Second, the type of hash
1, is written to the redis
r.hset("name","wyj",'{"cat":"1","small":"2"}') #大key + key +value
2, the data acquired in redis
r.hget("大key",”key“)
3, delete data
r.hdel("大key",”key“)
Third, Spoken
r.keys () # Get all of the key
r.type () # get the key type
r.flushall () # Empty all contents of all databases
r.flushdb () # clear the current data inside the database
r.exists ( "" key) # key to determine whether there is
