You may be aware that @gtg has established a public testnet. He has also set up a condenser front-end (testblog.openhive.network) which is extremly handy.
Prior to this, all of the devportal tutorials that demonstrate broadcast capabilities assume a local testnet that you deploy before executing the example code.
I have tested the python tutorials and verified that they also work on the public testnet. If you're wondering how to do this yourself, here's an example:
https://developers.hive.io/tutorials-python/witness_listing_and_voting.html
git clone https://gitlab.syncad.com/hive/devportal.git
cd devportal/tutorials/python/22_witness_listing_and_voting
pip install -r requirements.txt
python index.py
In this tutorial, the code example has (index.py):
client = Hive('http://127.0.0.1:8090', keys=[wif_active_key])
To use the public testnet instead of a local testnet, simply change this line to:
client = Hive('https://testnet.openhive.network', keys=[wif_active_key])
For this particular example, you can vote for a witness like gtg-rc1-19 or start your own testnet witness and vote for yourself.
To get a list of all witnesses on the testnet:
curl -s --data '{
"jsonrpc": "2.0",
"method": "database_api.get_active_witnesses",
"id":1
}' https://testnet.openhive.network
See: database_api.get_active_witnesses
While we have a condenser front-end, these more advanced capabilities might have to wait for additional devops resources, therefore many of these tutorials might come in handy while we wait.
