Flake8 PEP 3101 plugin

Python has three string formatting options:

• the old percent operator
• the .format() string method
• f-strings_ (only since python 3.6+)

Although f-strings are more ergonomic, there a certain scenarios where the .format() method is still the only viable option.

See pyformat website_ for examples of the percent operator vs the format() method.

For a more format definition see the PEP 3101_.

This plugin is based on a python checker that was in plone.recipe.codeanalysis_.
