The 927ness of it was discussed at length prior to implementation. PEP
498 isn't really another competing string format operation; it's more
like an alternative expression format. It's more in competition with
this:
msg = "The sum of " + str(x) + " and " + str(y) + " is " + str(x+y) + "."
which puts the interpolated expressions at the "correct place" in the
string - but at the cost of being verbose, messy, and error-prone.
Compare:
msg = f"The sum of {x} and {y} is {x+y}."
(Yes, there's a slight semantic difference; the latter uses format()
rather than str(). But otherwise, it's compiled to the "".join(...)
equivalent of the repeated concatenation example.)
