Introduction
<p dir="auto">In this series I will share my experience of building a Steemit bot with the python library. I'll post my functions used as a basis for my bot and try to explain it. The final goal will be to develop a high level API build on top of the Steem-Python library to make bot development easy.
<h4>Requirements
<h5>1. Python 3.6
<h5>2. steem-python
<p dir="auto">I personally use Windows and it was quite challenging to install the library but this <a href="https://steemit.com/utopian-io/@holger80/how-to-install-steem-python-for-windows" target="_blank" rel="nofollow noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">tutorial helped me a lot.
<h4>The Code
<h5>1. Setup
<p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517615804/fg7ctkqn17vcjm6lwj2l.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517615804/fg7ctkqn17vcjm6lwj2l.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517615804/fg7ctkqn17vcjm6lwj2l.png 2x" />
<p dir="auto">Just like in the last tutorial we need to import the library and initialize the Steem class.
<h5>2. The function
<p dir="auto">The new function <code>get_voter() basically uses the already existing <code>get_active_votes function but makes it easier to use.
<p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517615260/jerlvi130qshiqersu40.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517615260/jerlvi130qshiqersu40.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517615260/jerlvi130qshiqersu40.png 2x" />
<p dir="auto">The old function takes two inputs and we will combine these into one input ("post_identifier") and later split them into two again.
<p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517615552/cfp1mf3byfepx3ffhgsi.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517615552/cfp1mf3byfepx3ffhgsi.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517615552/cfp1mf3byfepx3ffhgsi.png 2x" />
<p dir="auto">After excuting the function, it returns a list like stated in the offical documentation.<br />
<img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517616183/jnxf7g4vxadsclb62snm.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517616183/jnxf7g4vxadsclb62snm.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517616183/jnxf7g4vxadsclb62snm.png 2x" />
<p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517616307/amx2jjo9bbzazlsvmrak.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517616307/amx2jjo9bbzazlsvmrak.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517616307/amx2jjo9bbzazlsvmrak.png 2x" />
<p dir="auto">In this example we only want the username of the upvoters but you could also extract other usefull informations like the voting weight.
<p dir="auto">To isolate this information we need to create a new empty list <code> voter = [] and then add the value of <code>'voter' to it, every step of a <code>for loop.
<p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517616738/rckmz5g2pnfdu78zpest.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517616738/rckmz5g2pnfdu78zpest.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517616738/rckmz5g2pnfdu78zpest.png 2x" />
<p dir="auto">But before we return the list in the next line we filter out our own upvote in line 13. This will prevent possible further errors with double votes.
<p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517617345/i53riwyxgj5cfpc67dqr.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517617345/i53riwyxgj5cfpc67dqr.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517617345/i53riwyxgj5cfpc67dqr.png 2x" />
<h5>3. Execution
<p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517617381/yyktptbg3te9zyakzyce.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517617381/yyktptbg3te9zyakzyce.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517617381/yyktptbg3te9zyakzyce.png 2x" />
<p dir="auto">The executed function will return a list like this:
<p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517617244/bkpdmedlg7imlp3ph1ub.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517617244/bkpdmedlg7imlp3ph1ub.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517617244/bkpdmedlg7imlp3ph1ub.png 2x" />
<p dir="auto">As mentioned earlier you only need to provide one argument:
<p dir="auto"><img src="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517617527/orkmiaoaxh8fuuqizjzb.png" alt="image.png" srcset="https://images.hive.blog/768x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517617527/orkmiaoaxh8fuuqizjzb.png 1x, https://images.hive.blog/1536x0/https://res.cloudinary.com/hpiynhbhq/image/upload/v1517617527/orkmiaoaxh8fuuqizjzb.png 2x" />
<h4>How to get the "post_identifier"

We can use a faster and updated version of this code to get the "post_identifier" (Thanks to <a href="/@emrebeyler">@emrebeyler!).

Hey, first I want to let you know, I saw your bot gave me test upvote. As long as I'm getting upvotes it is working, if I don't get an upvote, it is broken! ;-)))
On a more serious note, thanks, that you are adding in your tutorial json output, so we can see exactly where is the data you are extracting. How do you get such a nice output? In my case everything is clobbered in one long multi line and I can't make the sense of it. What tool do you use?
One more thing, your tutorials are well thought, with plenty of important information that beginners and wanna-be like me needs it, good job and I hope you continue ;-)
Thanks for the feedback! :)
<p dir="auto">To get a readable output I use python's build in module <code>pprint. <ol> <li><code> import pprint <li><code>pprint.pprint(your_json)O cool, thanks will thy this out!
