Let's say you have obtained custom_json from account history using the get_account_history method of a Steem Account (using Steem Python for example) but are looking for a way to reassemble and work with the data without having comprehensive knowledge of the necessary regex (regular expression) needed to work with the data.
In my case, I am trying to put back together a post identifier so need to use the author and permlink values. I set up a function to assist me with this in the future after a bit of tinkering and research.
import ast
def reassemble_dict(jsonstr):
split = jsonstr.split('["reblog",')[1]
split = split(']')[0]
json_dict = ast.literal_eval(split)
return json_dict
As an added bonus, I will be sharing my get_reblog function to help you understand the context:
def get_reblogs(user,steem)
a = Account(user,steem)
cjson = []
reblog = []
hist = a.get_account_history(-1,10000, filter_by=["custom_json"])
for h in hist:
cjson.append(j)
for j in cjson:
if 'reblog' in j['json']:
reblog.append(j)
return reblog
The above will return a list of dictionaries but it just so happens that the json attribute will be of type string which I find mighty inconvenient. Anyways, this function will get the job done when you pass that string as a parameter. Hope it helps.
You may be wondering why I pass my steem instance to my functions and, to be honest, I don't rightly know spare it seemed to have resolved some issues I has having a while ago. It may not be needed but I am one to operate under the philosophy "If it isn't broke, don't fix it" so have opted to leave it the hell alone.
