Python 3.6 should be python3.6

<p dir="auto">Also, I had a problem installing pycurl, so do this first:<br /> <code>sudo apt install libcurl4-openssl-dev libssl-dev<br /> then<br /> <code>python3.6 -m pip install pycurl <p dir="auto">Another problem when I run it:<br /> <code>FileNotFoundError: [Errno 2] No such file or directory: '/home/drak/SteemYaLater/Backups/drakos' <p dir="auto">So I created that folder manually, then I run the tool again, it fetches the posts but when it starts downloading them, it spits out binary characters on the screen.
