python与redis的交互

#pip install redis
import redis

#1.链接数据库  key——value       db=0 默认链接第0个数据库
client=redis.StrictRedis(host='127.0.0.1',port=6379)
#2.设置key
key='pyone'
# #3.string  增加   ：true/false
# res=client.set(key,'1')
# print(res)
# #4.删 ：1/0
# # res=client.delete(key)
# # print(res)
#
# #5.改：就是重新设置
# res=client.set(key,'2')
# print(res)

#6.查看值：-bytes
# res=client.get(key)
# print(res)
#查看所有的key：
res=client.keys()
print(res)
