Setup <p dir="auto">We first need to import some necessary librarys and set up a variable (we need it later). <p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517701743/tldg0wh92y6iint6jlha.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517701743/tldg0wh92y6iint6jlha.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517701743/tldg0wh92y6iint6jlha.png 2x" /> <p dir="auto">Obviously, we need to specify a node to connect to.<br /> Then you need to change <code> account to your own account name and add your <code> private posting key and your <code> private active key in order to be able to upvote later. <p dir="auto">With this information set, we can finally initialize the steem class. <p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517701881/kd7t3gg0b2dflt5eqgmw.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517701881/kd7t3gg0b2dflt5eqgmw.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517701881/kd7t3gg0b2dflt5eqgmw.png 2x" /> <h5>2. <code> relike() <p dir="auto">(The first two functions we use are explained in detail in my <a href="https://steemit.com/utopian-io/@wil1liam/steemit-python-bot-or-part-1-how-to-find-someone-s-newest-post" target="_blank" rel="noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">last two tutorials) <p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517704993/erkrexfdvpyxisbtl6ui.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517704993/erkrexfdvpyxisbtl6ui.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517704993/erkrexfdvpyxisbtl6ui.png 2x" /> <p dir="auto">In the beginning, we need to know what our newest post is and therefore we input our username in the <code> get_newest_post function, which returns the "post identifier" of our post ( Author + Permalink). <p dir="auto">Now we can build on top of that and get a list of the users who upvoted our post with the <code> get_voter function. <p dir="auto">Finally we just pass this list into our new <code> upvote_newest_post function and it will upvote their posts. <p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517703246/fq8wkd00grdsrpmfx5qa.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517703246/fq8wkd00grdsrpmfx5qa.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517703246/fq8wkd00grdsrpmfx5qa.png 2x" /> <h5>3. <code>upvote_newest_post() <p dir="auto">Because the upvote function of the python-steem library needs your account-name we need to pass it into the function. Secondly, we need the "post identifier" to know what post to upvote. <p dir="auto">This function will basically just go over every entry in the list of people who upvoted our post and finds their newest posts and then upvotes them. <p dir="auto">To do this we start with a for loop : <code> for i in usernames and then <code> get_newest_post(i) ( get the newest post for every entry in the list). <p dir="auto">In the end, we just <code>try to upvote the post and if this fails ( we already upvoted this post ) we will <code> except this error and just continue running the script. <p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517704006/nmwfpcnvfdjdhljmc2zp.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517704006/nmwfpcnvfdjdhljmc2zp.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517704006/nmwfpcnvfdjdhljmc2zp.png 2x" /> <p dir="auto">As you can see I set <code> weight to 100: this means that you will upvote the post with 100% voting power. You can of course change this number if you wish. <p dir="auto">( If your weight is -100 you will downvote the post -- please don't do that :) ) <h5>3. <code>main loop <p dir="auto">To let the bot run infinitely we make a <code> while(1) loop. ( 1 == always true ) <p dir="auto">Because I personally had problems with the bot stopping I added one line which debugs the time to let you know if it's still running.<br /> Now just execute the <code>relike function with your account name as the one and only input. <p dir="auto">Because it is unnecessary to execute this code every second [ it will put load on the API --> slows other people down :( ] I let it execute every 5 minutes. <p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517704761/e1qdmatvclzdvdddyqj9.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517704761/e1qdmatvclzdvdddyqj9.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517704761/e1qdmatvclzdvdddyqj9.png 2x" /> <h2><a href="https://github.com/ko-redtruck/steemit-relike-bot" target="_blank" rel="noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">Complete Code on Github <h4>Curriculum <ul> <li><a href="https://utopian.io/utopian-io/@wil1liam/steemit-python-bot-or-part-1-how-to-find-someone-s-newest-post" target="_blank" rel="noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">Part 1: How to find someone's newest post <li><a href="https://steemit.com/utopian-io/@wil1liam/steemit-python-bot-or-part-2-how-to-return-a-list-of-the-people-who-upvoted-your-post" target="_blank" rel="noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">Part 2: How to return a list of the people who upvoted your post <p dir="auto"><br /><hr /><em>Posted on <a href="https://utopian.io/utopian-io/@wil1liam/steemit-python-bot-or-part-3-relike-someones-post-if-they-liked-yours" target="_blank" rel="noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">Utopian.io - Rewarding Open Source Contributors<hr /><p>
