Python’s f-strings are an improved string formatting syntax. They’re string literals with an f at the beginning, outside the quotes. Expressions that appear in embedded curly braces ({}) are replaced with their values in the formatted string. Strings are sequences of characters.

Also called formatted string literals, f-strings are string literals that have an f before the opening quotation mark. They can include Python expressions enclosed in curly braces. Python will replace those expressions with their resulting values. So, this behavior turns f-strings into a string interpolation tool. Use built-in Python functions with characters and strings.
