Formatted string literals, known as f-strings, were introduced in Python 3.6 to allow embedding expressions inside string literals using curly braces {}. They enhance code readability and conciseness by enabling direct inclusion of variables and expressions within strings, prefixed with an 'f' or 'F'. F-strings are particularly useful for developers seeking a more efficient and readable way to format strings in Python.
