浅析python redis的连接及相关操作

import redis
r = redis.Redis(host='192.168.2.22',port=6379,db=2,password= 'redis')
r.set('name','Delia')    # 在redis里面放置对应的key,value
v = r.get('name')      # 获取key值对应的value值
print(v)

import redis
pool = redis.ConnectionPool(host='192.168.2.22', port=6379, db=2, password='redis')
r = redis.Redis(connection_pool=pool)
r.set('name','Delia')    # 在redis里面放置对应的key,value
v = r.get('name')      # 获取key值对应的value值
print(v)

import redis
pool = redis.ConnectionPool(host='192.168.2.22', port=6379, db=2, password='redis')
r = redis.Redis(connection_pool=pool)
r.mset({'name':'Delia','age':'18'})   # mset(mapping='')，批量设置值 {k1 = '' ,k2 = ''}
v = r.mget({'name','age'}) # 批量获取值
print(v)

import redis

r = redis.Redis(connection_pool=pool)
r.set('name','Delia1234')
r.setrange('name',4,'00')   #setrange(name,offset,value)修改字符串内容，从指定位置开始替换
v = r.getrange('name',4,5) #getrange(key,start,end)获取子序列
print(v)
