PY: Get Account Comments

Fetch list of comments made by account on posts or comments.

Full, runnable src of Get Account Comments can be downloaded as part of the PY tutorials repository.

In this tutorial will explain and show you how to access the Steem blockchain using the steem-python library to fetch list of posts to randomize account list and get replies of selected account.

Intro

Steem python library has built-in function to get comments list made by specific account. Since we don’t have predefined account list, we will fetch newly created posts and show their authors for selection and give option to choose one account to get its comments. get_discussions_by_comments function fetches list of comments made by account. Note that get_discussions_by_created filter is used for fetching 5 posts and after selection of its author tutorial uses author of the post to fetch that account’s comments.

Steps

  1. App setup - Library install and import
  2. Post list - List of posts to select from created filter
  3. Comments list - Get comments list made by selected account
  4. Print output - Print results in output

1. App setup

In this tutorial we use 3 packages, pick - helps us to select filter interactively. steem - steem-python library, interaction with Blockchain. pprint - print results in better format.

First we import all three library and initialize Steem class

    import pprint
    from pick import pick
    # initialize Steem class
    from steem import Steem

    s = Steem()

2. Post list

Next we will fetch and make list of accounts and setup pick properly.

    query = {
      "limit":5, #number of posts
      "tag":"" #tag of posts
    }
    #author list from created post list to randomize account list
    posts = s.get_discussions_by_created(query)

    title = 'Please choose account: '
    options = []
    #accounts list
    for post in posts:
      options.append(post["author"])

    # get index and selected account name
    option, index = pick(options, title)

This will show us list of accounts to select in terminal/command prompt. And after selection we will get account name as a option variable.

3. Comments list

Next we will form another query to get comments list of account

  query2 = {
    "limit":5, #number of comments
    "start_author":option #selected user
  }

  # get comments of selected account
  comments = s.get_discussions_by_comments(query2)

Note that start_author variable in query should be account name so that get_discussions_by_comments can provide us corrent information.

4. Print output

Next, we will print result, comments of selected account and details of each comment.

  # print comment details for selected account
  pprint.pprint(comments)
  pprint.pprint("Selected: "+option)

The example of result returned from the service is a JSON object with the following properties:
