redis基本命令的演示:

import redis 

r = redis.Redis(host='127.0.0.1', port=6379,db = 0)
#查看匹配redis的数据
r.keys()
#查看redis的大小
r.dbsize()
#设置redis的key/value值
r.set('foo','zoo')
#获取redis的对应键值的value
r.get('foo')
#删除redis的所有数据
r.flushdb()

#查看是否存在某个键值
r.exists('key')

>>> import redis
>>> r = redis.Redis(host='127.0.0.1', port=6379)
>>> r.set('foo','zoo')
True
>>> g.get('foo')
Traceback (most recent call last):

>>> r.get('foo')

>>> r.dbsize()

>>> r.delete('too')

>>> r.keys()

>>> r.save()
True
>>> r.get('wu')
'yanlong'
>>> a = r.get('wu')
>>> dir(a)
