Thank you, I tried yesterday and I got some error.
But I just uninstalled steem and replaced it with:
pip install -U git+git://github.com/Netherdrake/steem-python
And some of my problems are solved. One code (start following a member) is working, so finally I'm having the progress. Thank you for your reply. I may come there later if I'm still going to struggle with anything.
If you are still having issues it is generally quicker to contact us on Discord
