Preparing Actions for Python 3 Compatibility

CloudBolt is aiming to support Python 3 by version 8.0, and any custom Plug-ins or Actions must also be updated before upgrading. Here is a brief guide to updating your Python code to be compatible with both Python 2 and 3.

Raising exceptions should also use a method to set a specific error message:


Catching exceptions need to use 'as' instead of a comma:


Here are a few excellent resources on the topic that can provide more detailed information:
