Another way of doing things would be using SteemData, @furion's website which is pretty awesome! And already has a python library 😊

while initiating the Steem object, in this line:

s=Steem()

instead, pass the url of the RPC node in the Steem() method

so like this:

s=Steem("<RPCNodeUrl>")

Ok, thank, I will try that and the library from @furion 👍
