Python 5 data types for REDIS operations

1. Connect to Redis (two ways)

• 1  # Decode_responses=true: Resolving the obtained value type is a bytes byte problem 2  R = Redis. Redis (host='localhost', port='6379', db=0, decode _responses=true)

• 1  Pool = Redis. ConnectionPool (host='localhost', port=6379, db=0, decode_responses=True)2   r = Redis. Redis (Connection_pool=pool)

2. string-type String

1  #ex Expiration Time unit seconds s2R.set ('name','Jack', ex=20)3RST = R.get ('name')4  Print(RST)5  6  7Results:"Jack"

3. Listing Type list

1R.lpush ('Object',' One')2R.lpush ('Object',' Both')3R.lpush ('Object','three')4R.lpush ('Object',' Four')5R.lpush ('Object','Five')6R.lpush ('Object','Six')7ret = R.lrange ('Object', 0, 5)8  Print(ret[::-1], Len (ret))9    Ten    OneResults: [' One',' Both','three',' Four','Five','Six'] 6

4. Hash type hashes

1R.hset ('User:info','name','Jack')2R.hset ('User:info',' Age', 20)3R.hset ('User:info','Phone','18712909999')4R.hset ('User:info','Email','[email protected]')5RST = R.hgetall ('User:info')6  Print(RST)7 8 9Result: {' Age':' -','Email':'[email protected]','name':'Jack','Phone':'18712909999'}

5. Collection type set

1R.sadd ('Set',' One')2R.sadd ('Set',' Both')3R.sadd ('Set','three')4res = R.smembers ('Set')5  Print(RES)6 7 8Result: {' Both',' One','three'}

6. Ordered collection type sorted set

1R.zadd ('Mark',' One', 1)2R.zadd ('Mark',' Both', 2)3R.zadd ('Mark','three'-R)4R.zadd ('Mark',' Four', 4)5R.zadd ('Mark','Five', 5)6result = R.zrange ('Mark', 0, 10)7  Print(Result)8 9 TenResults: [' One',' Both','three',' Four','Five']
