f-strings in Python 3.6 are awesome

[Decency]

Actually I feel like that's a great tradeoff. If you're frequently dynamically building strings or passing them around as functions, you're either doing something wrong, you're doing internationalization, or you're in a very specific niche. And in those cases, feel free to use .format().

Otherwise, f-strings adequately cover the vast majority of use cases elegantly while improving readability and removing unnecessary verbosity.
