At the moment it is not possible for most accounts to publish a post through condenser. This state will be resolved when https://api.steemit.com has replayed and works with version 0.20.3. There are other full nodes that already have replayed, as https://api.steem.house for example. With beem, it is therefore possible to publish a post.
Install beem
pip install beem -U
or
conda install beem
Store the following script as publish_post.py file
#!/usr/bin/python
from beem import Steem
import getpass
if __name__ == "__main__":
author = "holger80"
title = "How to write a post when all condensers are not useable"
with open('body.md') as f:
body = f.read()
parse_body = True
tags = ["steem", "python", "beem"]
wif = getpass.getpass(prompt='Enter your posting key.')
stm = Steem(node="https://api.steem.house", keys=[wif])
stm.post(title, body, author=author, tags=tags, parse_body=parse_body, self_vote=False)
Store your post body in body.md
Write your post with an editor and store it as body.md in the same directory as the python script.
Publish your post
You can now publish your post with:
python publish_post.py
Enter your posting key into the prompt and the post will be posted.
