How is it implicit? Every insertion is expressed in exactly the place where it will print. It's way more explicit than having a placeholder and a value on compl

  > It's way more explicit than having a placeholder and a value on completely different parts of the expression. No its not.

    "My name is {}, I'm {}'{}'' tall and live in {}".format(name, location, feet, inches) This error is much better hidden than in the equivalent: f"My name is {name}, I'm {location}'{feet}'' tall and live in {inches}."

      I did mention named parameters, you are using positional parameters to make your point. You don't even list the variables in your example. That seems pretty implicit to me. I think this is more explicit: "My name is {name}, I'm {feet} tall and live in {location}.".format(name="Bob", location="USA", feet=7)

        Your example is not representative because you're using literals. Your actual example would be: "My name is {name}, I'm {feet} tall and live in {location}.".format(name=name, location=location, feet=feet) And with f-strings: f"My name is {name}, I'm {feet} tall and live in {location}." f-strings is clearly more readable, concise and actually faster to run.

          The literals were just an example. And personally I find it more explicit, which is my original point. If its faster to run, then fair enough.

            Using your example, I think "My name is {name}, I'm {feet} tall and live in {location}.".format(name="Bob", location="USA", feet=7) is less explicit than "My name is Bob, I'm 7 feet tall and live in USA."

              Yes it is.

              and that last one is faster to run ;-)
