Python Ask Wikipedia

Ask Wiki an question, get an answer.

• 1: Intent Script
  

If you dont have it already, create the file intent_script.yaml in the /config dir and fill in the code below.
(dont forget to reference it in configuration.yaml with intent_script: !include intent_script.yaml

• 2: Custom Sentence
  

Create a folder called custom_sentences inside your /config dir.
Inside that folder, once again create a folder named with your language code. sv for swedish, en for english.
In that folder you create a file and name it whatever you want, but remember it, cause it will be referencesd later.
I will use IntentName.yaml as an example here, fill this yaml file with the code from below.

• 3: Shell command
  

If you dont have it already, create the file shell_command.yaml in the /config dir and fill in the code below.
(dont forget to reference it in configuration.yaml with shell_command: !include shell_command.yaml

• 4: Python Script
  

Create the file ask_wiki.py inside your /config folder.
Paste in at bottom of this page, and fill in your Home Assistant information.
