Then, Python formats the result using the .__format__() special method under the hood. This method supports the string formatting protocol. This protocol underpins both the .format() method, which you already saw, and the built-in format() function:...
Format strings contain “replacement fields” surrounded by curly braces {}. Anything that is not contained in braces is considered literal text, which is copied unchanged to the output. If you need to include a brace character in the literal text, it can be escaped by doubling: {{ and }}...
