Two unrelated things share the name "Anaconda" here. Anaconda the Python distribution (anaconda.com) is what you installed. Anaconda the Sublime Text plugin is what your settings file configures (those keys, auto_formatting, pep8_ignore, anaconda_linter_*, are plugin-specific).
The error is the plugin failing to run autopep8. Usually that's because autopep8 isn't installed in the interpreter the plugin points at. Open Anaconda Prompt, pip install autopep8, then add this to your plugin settings with the actual path:
"python_interpreter": "C:/Users/YourName/anaconda3/python.exe"That said, the Sublime Anaconda plugin has been basically unmaintained for years. If you just want to keep moving on Corey's tutorials, VS Code with the official Python extension will save you a lot of these fights.
