How to store and retrieve a dictionary with redis

Question

# I have the dictionary my_dict my_dict = {     'var1' : 5     'var2' : 9 } r = redis.StrictRedis() 

How would I store my_dict and retrieve it with redis. For example, the following code does not work.

#Code that doesn't work r.set('this_dict', my_dict)  # to store my_dict in this_dict r.get('this_dict')  # to retrieve my_dict 

Answer 1

You can do it by hmset (multiple keys can be set using hmset).

hmset("RedisKey", dictionaryToSet)

import redis conn = redis.Redis('localhost')  user = {"Name":"Pradeep", "Company":"SCTL", "Address":"Mumbai", "Location":"RCP"}  conn.hmset("pythonDict", user)  conn.hgetall("pythonDict")  {'Company': 'SCTL', 'Address': 'Mumbai', 'Location': 'RCP', 'Name': 'Pradeep'}

you can pickle your dict and save as string.

import pickle import redis  r = redis.StrictRedis('localhost') mydict = {1:2,2:3,3:4} p_mydict = pickle.dumps(mydict) r.set('mydict',p_mydict)  read_dict = r.get('mydict') yourdict = pickle.loads(read_dict)
