So, you do need to know that all three exist (e.g., for maintaining code), but you can easily choose the style that you prefer and just use that.

Largely tangential, but don't you mean "all four"? PEP-292 template
strings are also still around, though I don't recall that I've ever
seen them used in the wild.

When I read that Python 3.6 would include f-strings, I turned to the
coworker sitting next to me and said, "Oh my god, Python is adding yet
another new syntax for string formatting." It's getting to be a joke.
