python常用模块-redis操作

python的redis模块比较简单，我们常用的，无非是【配置连接】、加上【增删等相关操作】。。。

import redis
from data.pwd import redis_pwd
client = redis.Redis(host='127.0.0.1',port=6379,password=redis_pwd,db=0)
# 1. 设置值
client.set('username','admin')
client.hset('student','name','bernard')
client.hset('student','age','40')

# 2. 拿值
client.keys("*")
client.get('username')
client.hget('student')

# 3. 删除值--一般先判断是否存在
iskey = client.exists("uername")
if iskey:
client.delete('username')
else:
print("there is no key existing that you find...")

# 4. key的剩余生命时长
client.pttl("student")
# 5. 设置过期时间
is_expire = client.expire('student',2)

# 6. 输出返回的随机key的值 he 类型
key1 = client.randomkey()
keyType =client.type(key1)
