Python Praw ways to store data for calling later?

Question

Is a dictionary the correct way to be doing this? Ideally this will be more then 5+ deep. Sorry my only language experience is powershell there I would just make an array of object. Im not looking for someone to write the code I just wanna know if there is a better way?

Thanks Cody

My Powershell way:

[$title1,$title2,$title3]

$titleX.comment = "comment here"
$titleX.comment.author = "bob"
$titleX.comment.author.karma = "200"
$titleX.comment.reply = "Hey Bob love your comment." 
$titleX.comment.reply.author = "Alex"
$titleX.comment.reply.reply = "I disagree"

Python code Borken:

import praw


d = {}



reddit = praw.Reddit(client_id='XXXX',
                     client_secret='XXXX',
                     user_agent='android:com.example.myredditapp:'
                     'v1.2.3 (by /u/XXX)')

for submission in reddit.subreddit('redditdev').hot(limit=2):
     d[submission.id] = {}
     d[submission.id]['comment'] = {}
     d[submission.id]['title']= {}
     d[submission.id]['comment']['author']={}
     d[submission.id]['title'] = submission.title
     mySubmission = reddit.submission(id=submission.id)
     mySubmission.comments.replace_more(limit=0)
     for comment in mySubmission.comments.list():
        d[submission.id]['comment'] = comment.body
        d[submission.id]['comment']['author'] = comment.author.name

print(submission.title)
print(comment.body)
print(comment.author.name)
print(d)

  File "C:/git/tensorflow/Reddit/pull.py", line 23, in <module>
    d[submission.id]['comment']['author'] = comment.author.name

TypeError: 'str' object does not support item assignment

I think your approach using a dictionary is okay, but you might also solve this by using a data structure for your posts: Instead of writing

d[submission.id] = {}
d[submission.id]['comment'] = {}
d[submission.id]['title']= {}
d[submission.id]['comment']['author']={}
d[submission.id]['title'] = submission.title

you could create a class Submission like this:

class Submission(object):
    def __init__(self, id, author, title, content):
        self.id = id
        self.author = author
        self.title = title
        self.content = content
        self.subSubmissions = {}

    def addSubSubmission(self,submission):
        self.subSubmission[submission,id] = submission
    def getSubSubmission(self,id):
        return self.subSubmission[id]

by using you could change your code to this

submissions = {}
for sm in reddit.subreddit('redditdev').hot(limit=2):
    submissions[sm.id] = Submission(sm.id, sm.author, sm.title, sm.content)

    # I am not quite sure what these lines are supposed to do, so you might be able to improve these, too
    mySubmission = reddit.submission(id=sm.id)
    mySubmission.comments.replace_more(limit=0)
    for cmt in mySubmission.comments.list():
        submissions[sm.id].addSubSubmission(Submission(cmt.id, cmt.title, cmt.author, cmt.body))

By using this apporach you are also able to export the code to readout the comments/subSubmissions into an extra function which can call itself recursively, so that you can read infitive depths of the comments.
