Add site-package yamllint to inspect YAML/YML files for errors.

pip install –user yamllint

Yamllint has two default configuration files: default.yaml and relaxed.yaml with pre-set rules. Can extend a configuration file and alter one of the rules.

Mylint.yaml:

# Mylint.yaml is my own configuration file for yamllint
# It extends the default.yaml by adjusting some options.

extends: default

rules:
new-lines: disable

Did this to avoid the error about the EOL character on the first line (—).

1:4 error wrong new line character: expected \n (new-lines)
