Another example, of how I use py-steem by @xeroc.
This time I'm using the Blockchain class, that was part of steemtools by @furion.

This script will follow votes from authors in a list, called voter_list.
Just replace pk and account with your posting key(s) and account(s).

Code

from steem import Steem
from steem.blockchain import Blockchain
chain = Blockchain()

voter_list = ["felixxx"]
pk = ["5GH56thyouwishlol67zPO9hkO9HKP6gthz8"]
account = ["votebot"]

steem = Steem(keys=pk[0], node="wss://node.steem.ws")

for operation in chain.ops():
    op = operation["op"]
    if op[0] == "vote":
        #print(op) #uncomment this to get an idea of the format
        comment_voter = op[1]["voter"]
        if comment_voter in voter_list:
            comment_link = op[1]["permlink"]
            comment_author = op[1]["author"]
            vote_weight = int(op[1]["weight"]/100)
            comment = steem.get_post("@" + comment_author + "/" + comment_link)
            if comment.is_main_post():
                print("vote by: " + comment_voter + " for " + comment_link + " weight:" + str(vote_weight)) 
                for (k,v) in enumerate(account): 
                    try:
                      steem = Steem(keys=pk[k], node="wss://node.steem.ws")
                      comment.vote(vote_weight, v) 
                      print("... followed with " + v + " with " + str(vote_weight) + "%")
                    except Exception as e:
                      print("... NOT followed with " + v + " because:")
                      print(str(e))

Known issues:

• This bot might try to cast multiple votes within too little time ( When multiple accounts in voter_list vote at the same time )

---

At the end of the day, this script does nothing more than streemian can already do.
( While streemian is more reliable )

However, I can now try out to take a vote by a trusted author to trigger an event.
Next function I will include is vote_check, like I use for @deutschbot, to see if other trusted authors have already liked the comment, with a treshold from 0-1.

Code

def vote_check(c_comment, curators, threshold):
    votercount = 0
    checked = False
    check_comment = steem.get_content(c_comment.identifier)
    for avote in check_comment['active_votes']:
        if (avote['voter'] in curators and avote['percent'] > 0):
                votercount = votercount + 1            
    vote_ratio = (votercount / len(curators))
        if vote_ratio >= threshold:
        checked = True
    return checked

I post these examples, so you have some working examples of code.
Both functions are tested and work.
They are not very clever and might cause some issues, but it's something to build up on.

I don't believe curation should be done with simple algorithms.
I, personally, would maybe deploy the first script, for when I'm on holiday, so I can just follow someone I trust in his curation-efforts.
Mainly, this post is for educational purposes.

I would really appreciate if more people tried this out, so I have someone to talk to, when I run into problems.

Have fun !
