Hello Steemit,

yesterday i was wondering how difficult it actually is, to write a simple vote or post bot for the "introduceyourself" section. (Like @wang is doing it)

With the help of https://github.com/xeroc/python-steemlib it was actually quite easy. (I had no experience with python before). @xeroc did an amazing job with the library!

For all other user, who want to start programming on steemit:

## Full python code for upvote every new post @introduceyourself

    import time

    from steemapi.steemnoderpc import SteemNodeRPC
    from steembase import transactions

    currentTime = int(time.time())

    user = "yourUsername"
    wif = "yourWifKey"
    category = "introduceyourself"

    rpc = SteemNodeRPC("wss://steemit.com/wstmp3")
    for post in rpc.stream("comment", start=currentTime):
        if post["parent_author"] == '' and post["parent_permlink"] == category:
            try:
                expiration = transactions.formatTimeFromNow(60)
                op = transactions.Vote(
                        **{"voter": user,
                           "author": post["author"],
                           "permlink": post["permlink"],
                           "weight": int(10000)}
                )
                ops = [transactions.Operation(op)]
                ref_block_num, ref_block_prefix = transactions.getBlockParams(rpc)
                tx = transactions.Signed_Transaction(
                        ref_block_num=ref_block_num,
                        ref_block_prefix=ref_block_prefix,
                        expiration=expiration,
                        operations=ops)
                tx = tx.sign([wif])

                tx = transactions.JsonObj(tx)

                # Broadcast JSON to network
                rpc.broadcast_transaction(tx, api="network_broadcast")

                print("Voted!")
                print(post["title"])
            except Exception:
                print("Oops! Maybe already voted or voted to often")

You can see the second part (the post bot) here: https://steemit.com/hacking/@seagul/steemit-post-bot-like-wang-for-introduceyourself
