Style guidelines

Full list at https://www.flake8rules.com Travis will check linting automatically for all commits (including pull requests), you can run flake8 with the required commands to get equivalent results.

Ignored (should not be followed):

• W191 ignored - Use tabs instead of spaces
• E117 ignored - Over-indented allowed as a consequence of W191
• E501 ignored - No line-length limit as chatbot responses are long

Consequently (have to be followed):

• E123 - closing bracket should match indentation of opening bracket's line
• E126 - continuation line over-indented for hanging indent (one indent only)
• W504 - line break after binary operator not allowed since E501 is ignored (no line-length limit)
