If you are coming to Python from languages like Java, C#, or Go, one of the first things you might search for is a StringBuilder class. You know the drill: strings are immutable, and concatenating them in a loop is a performance killer. You look through the Python standard library, expecting to find string.Builder, but it isn’t there.
