Very cool to see you make this bot! I like it :D I got some feedback for you anyways.
I would probably make the info command show a lot more information. For one part I do think that you should display at least one more digit to the reputation as especially when you are in the higher range, your reputation doesn't change for a long time, and it would be disappointing to only see the full number ;)
Also, I would highly recommend you to show the SBD and STEEM in the savings as well for the info command. You could make this for example by making it like that (as a return to ?info steemit in the STEEM Balance field): 2,000,000.580 (2,806,644.632) STEEM
I think the vested balance is also a very important piece of information on the steem blockchain that should be included in an info command. e.g. Hive account@utopian-io doesn't really look that "good" if you only see it's balance, but not it's SP :P
Now a little coding advice for you, that you could make use of in the future. Consider using the logging module (documentation) instead of printing the different things to the console. That makes it way more flexible and you'll just have a more convenient experince with logging stuff in the execution of your program.
Also, as far as I know, it's recommended to use other string formatting methods as they are easier to read and maybe have some other advantages as well. Instead of "These are last %s comments of %s" % (amount, username) you could just make it look that way: f"These are last {amount} comments of {username}". I think this is way more readable and highly improves your code look. Hive account@scipio made a tutorial on that way of formatting strings, and there is plenty of documentation for it as well if you want to look into it more. :)
On a final note: why did you change your name? "Some difficulties" isn't that much information ;)
Thank you for reading that wall of text,
