I always wanted to be able to save my Steem posts locally. After that better searching tools are available than the ones we have at the blockchain level.

I have only started poking around the development APIs for Steem, and this is the first script with a real purpose I've done in Python. On top of that, I'm also kind of new to Ubuntu. :)

If you are a dev and have been doing this for a while, you probably can write a more efficient script.

I wasn't looking for efficiency when I wrote it, I was interested to learn, and from there maybe others who are also Python beginners or haven't tried to code using Steem APIs. Hence the extensive comments.

Features and options:

saves all your markdown posts as .md files
saves all your raw HTML posts as .html files
you can set a main sub-directory or sub-path in the current directory where the files will be placed
posts will be placed in subdirectories based on the creation date (year-month) or primary tag - option to set at the beginning of the script
you can save the posts for any account
you can save resteemed posts as well or not
you can add tags at the end of the post or not
title is automatically added as H1 at the beginning of the post

I've tested the script on Python 3.7.4, but I believe it should work on earlier versions. Also the script is written for Linux/Ubuntu, for Windows you will need to adapt the parts of the script handling paths and creation of directories.

You will also need a good Markdown viewer/editor to see the saved files. I used Typora, but it looks like this will be a paid software when it exits beta version, so a good free alternative will be nice.

So, here's the Python script. Pay attention, settings are hard coded, you'll have to manually change them.

While I'm far from a Python or Steem dev expert, if you have questions let me know.

Feedback to improve from more experienced devs is welcomed as well. :)

Update: Edited the post because in the original there were some errors due to the copy-pasted code to html, which I haven't initially tested.
