redis python tutorial

Reproduced in: http://www.itxuexiwang.com/a/shujukujishu/redis/2016/0216/143.htmlThe various operational commands, operating mechanisms, and server initialization parameter configurations of Redis have been described in great detail in previous blogs. This blog is the last of a series of blogs that will give you code examples for accessing and manipulating Redis

Redis is a high-performance key-value database. The emergence of Redis, to a large extent, compensates for the shortage of such key/value storage in memcached, and in some cases can complement the relational database well. It provides a python,ruby,erlang,php client and is easy to use. Performance Test Results:Set operation 110,000 times per second, get operatio

Yesterday, we discussed how Python connects to Redis. Today we are going to learn how to manipulate Redis data in Python.Here, please add. Redis is a database in the form of Key-value. You can store data in multiple formats.Today, we are trying to do these common APIs.1. Set the data:R =

There are two types of errors in accessing Redis with Python today on this computer (Windows): If I am in the way of Sentinel, I will report unknown command ' SENTINEL ' such errors; If I match Strictredis, I will report Noauth authentication required. Error; Mark, find a way to solve it tomorrow .... PS: Finally found that the MONGO connection failure is the password is not set to cause (actually because

')The above key is Xinxin,value is the following data, log on to Redis on the operation results of the above code:2), to obtain value, you need to make a large key and small key to obtain the corresponding value, for example:Print (R.hget ('xinxin',' new '). Decode ()) # specify big key and small key to get corresponding data # Gets the result:1m8 100w Deposit3), get all the key and valuePrint (R.hgetall ('xinxin')) # get all the K and V inside4), d

Redis is an open-source non-relational database. it is written in C language and is a key-value storage system. it stores many value types, including string, list ), set, zset, and hash how to operate Redis using Python? The following example describes how to read and write Redis databases using
