My contest results and automatizing contests with steem-python!

I made a simple contest 5 days ago to celebrate my milestone of 100 followers. Since I have a trip to Ukraine tomorrow, I had to make the draw today.

Contest had two simple rules.

• Upvote the post
• Follow my account

I want to make this post also educational about the steem blockchain. So, I will share how I make the contest.

Getting voters list

Assuming that you have steem-python installed in your local environment, let's get the post details.

steem-python package has a class named Post. This includes all the stuff related with posts.

Let's get my contest post.

from steem.post import Post
post = Post('emrebeyler/100th-follower-milestone-sbd-giveaway-5-sbd-prize-pool')

Post object has some properties/methods inside. active_voters is something we can use to get the voter list. But taking the list is not enough, also I want to enumerate them and dump list into a text file so I can use random.org to select a number and match with the winners. Also I need to check each voter that if they follow me or not.

Let's get the voters list:

voters = [p.get("voter") for p in p.active_votes]

I need to know they follow me or not. Let's check it. To get the follower list of an account, we can use Account object in the steem-python.

account = Account('emrebeyler', Steem())
account.get_followers()

What I need now, is to find the intersection of my follower list and post upvoters. Python has a built-in type as set, which has a .intersection method. Let's use it.

This one-liner is what I need.

participants = set(account.get_followers()).intersection(set(voters))

Now I have the participant list. Most of the work is done, let's write them into a text file with numbers.

f = open ("/tmp/list.txt", "w+")
for index, voter in enumerate(participiants):
    f.write("%s - %s\n" % (index + 1, voter))
f.close()

All set!

After that point, I just went to random.org and get 3 random integers.

Congrats. @nickperry, @omersurer, @mahmutfirat. I will send your prizes in 5 minutes. Check your wallet.

Thanks to all my followers and participants. See you next time.

For turkish visitors;

Yüzüncü takipçim şerefine bir yarışma düzenlemiştim. Aylar öncesinden planlı Lviv gezimi unuttuğum için bugünden çekilişi yapmak durumunda kaldım. Oy verenlerin listesini alma, beni takip ediyorlar mı kontrolünü yapma gibi işlerini yine benim çılgın siyah konsolumdan yaparken, aslında bunu da öğretici bir şekilde yapabilirim belki diye, ingilizce kısmında nasıl yapıldığını anlattım.

Kazananlar @nickperry, @omersurer, @mahmutfirat oldu. Ödüllerini birazdan yollayacağım. Başka yarışmalarda görüşmek üzere!
