#使用redis pool
pool = redis.ConnectionPool(host="*",port=6379,password='*')
r = redis.Redis(connection_pool=pool)
#直接连接使用api
# r = redis.Redis(host='*',port=6379,password='*')

#info 指定参数
print(r.info(section='clients'))
print(r.info(section='Keyspace'))
#info 不指定参数，默认所有信息
# print(r.info())
# getset() 方法，返回旧值，同时赋洗你的值
r.set('test',1111)
print(r.get('test'))

print(r.get('test'))
#getrang() 子串(偏移量：offset: 0代表开始，-1代表结束)
print(r.getrange('test',-3,-1))
#setrange()替换子串(从偏移量开始)
r.setrange('test',0,'change')
print(r.get('test'))
#mset()一次设置多个键的值
r.mset({'pig':'111','ca':'222','app':'333'})
print(r.info(section='Keyspace'))
#mget()一次取多个键的值
print(r.mget(['pig','app']))
#delete 删除键
r.delete('pig')
print(r.get('pig'))
#批量删除
DelList=r.keys('*')
for key in DelList:
r.delete(key)
